Peter Chen ec447ab138 Doc: usb: chipidea: need to build both kernel Image and modules
When tried to enable OTG FSM, we need to rebuild both kernel Image
and modules, since there are some codes at gadget modules which are
controlled by related configurations.

Greg Kroah-Hartman f8712528ae usb: patches for v3.16 merge window
Not a lot here during this merge window. Mostly we just have
 the usual miscellaneous patches (removal of unnecessary prints,
 proper dependencies being added to Kconfig, build warning fixes,
 new device ID, etc.
 
 Other than those, the only important new features are the
 new support for OS Strings which should help Linux Gadget
 Drivers behave better under MS Windows. Also Babble Recovery
 implementation for MUSB on AM335x. Lastly, we also have
 ARCH_QCOM PHY support though phy-msm.

Petr Oros 7a9e6da11c doc: fix incorrect formula to calculate CommitLimit value
The formula to calculate "CommitLimit" value mentioned in kernel documentation is incorrect.
Right formula is: CommitLimit = ([total RAM pages] - [total huge TLB pages]) * overcommit_ratio / 100 + [total swap pages]

  - More moves towards full componentisation.
  - Removal of some unused I/O code.
  - Lots of cleanups, fixes and enhancements to the davinci, Freescale,

  - Several drivers exposed directly in Kconfig for use with simple-card.
  - New drivers for Cirrus CS42L56, Realtek RT5639, RT5642 and RT5651 and

" 1.      Update RCU documentation.  These were posted to LKML at

  2.      Miscellaneous fixes.  These were posted to LKML at

  4.      Variable-name renaming cleanup, sent separately due to conflicts.
          This was posted to LKML at https://lkml.org/lkml/2014/5/13/854.

  5.      Patch to suppress RCU stall warnings while sysrq requests are
          being processed.  This patch is the RCU portions of the patch
          that Rik posted to LKML at https://lkml.org/lkml/2014/4/29/457.
          The reason for pushing this patch ahead instead of waiting until
          3.17 is that the NMI-based stack traces are messing up sysrq
          output, and in some cases also messing up the system as well."

From CCCFG register of eDMA3 we can get all the needed information for the
driver about the IP:
Number of channels: NUM_DMACH
Number of regions: NUM_REGN
Number of slots (PaRAM sets): NUM_PAENTRY
Number of TC/EQ: NUM_EVQUE

The ti,edma-regions; ti,edma-slots and dma-channels in DT are
redundant since the very same information can be obtained from the HW.
The mentioned properties are deprecated.

Guenter Roeck 84899d394e hwmon: (emc1403) Make all hyst attributes except for temp1_crit_hyst read-only
All chips in this chip series only support a single hysteresis value. Having
multiple writable hysteresis attributes is therefore confusing, since a single
write affects all hysteresis temperatures. Make all but one (temp1_crit_hyst)
read-only.

Guenter Roeck 50bf46509f hwmon: (lm77) Do not preserve hysteresis when updating critical temp limit
Updating the hysteresis value when updating the critical temperature limit
was following the rule of 'least surprise'. However, it had the undesirable
side effect of changing the hysteresis for all other attributes, which
defeats the purpose of least surprise. In addition, it could result in
invalid hysteresis values if the resulting hysteresis was too large. In such
cases the resulting hysteresis ended up changed anyway, which again defeats
the purpose. So drop that code and document the new behavior.

Bjorn Helgaas 88a984ba07 DMA-API: Change dma_declare_coherent_memory() CPU address to phys_addr_t
dma_declare_coherent_memory() takes two addresses for a region of memory: a
"bus_addr" and a "device_addr".  I think the intent is that "bus_addr" is
the physical address a *CPU* would use to access the region, and
"device_addr" is the bus address the *device* would use to address the
region.

Rename "bus_addr" to "phys_addr" and change its type to phys_addr_t.
Most callers already supply a phys_addr_t for this argument.  The others
supply a 32-bit integer (a constant, unsigned int, or __u32) and need no
change.

Use "unsigned long", not phys_addr_t, to hold PFNs.

No functional change (this could theoretically fix a truncation in a config
with 32-bit dma_addr_t and 64-bit phys_addr_t, but I don't think there are
any such cases involving this code).

Bjorn Helgaas 77f2ea2f8d DMA-API: Clarify physical/bus address distinction
The DMA-API documentation sometimes refers to "physical addresses" when it
really means "bus addresses."  Sometimes these are identical, but they may
be different if the bridge leading to the bus performs address translation.
Update the documentation to use "bus address" when appropriate.

Also, consistently capitalize "DMA", use parens with function names, use
dev_printk() in examples, and reword a few sections for clarity.

No functional change; documentation changes only.

Andrew Lunn 7d6d478f38 ASoC: alc5623: Add device tree binding
Let the ALC5623 codec be instantiated from DT. Add a simple binding
for the additional control register and the jack detect register.

Also, add a prompt to the Kconfig entry for this CODEC, so that it can
be selected. Since kirkwood-t5325.c will no longer be used, we need to
be able to enable the CODEC in the mvebu_v5_defconfig etc.

Mike Snitzer 80c578930c dm thin: add 'no_space_timeout' dm-thin-pool module param
Commit 85ad643b ("dm thin: add timeout to stop out-of-data-space mode
holding IO forever") introduced a fixed 60 second timeout.  Users may
want to either disable or modify this timeout.

Allow the out-of-data-space timeout to be configured using the
'no_space_timeout' dm-thin-pool module param.  Setting it to 0 will
disable the timeout, resulting in IO being queued until more data space
is added to the thin-pool.

Dylan Reid 3c320f3f56 ALSA: hda - Add driver for Tegra SoC HDA
This adds a driver for the HDA block in Tegra SoCs.  The HDA bus is
used to communicate with the HDMI codec on Tegra124.

Most of the code is re-used from the Intel/PCI HDA driver.  It brings
over only two of the module params, power_save and probe_mask.

Merge "dts: socfpga: general updates for the socfpga platform" from Dinh
Nguyen:

Mostly DTS additions to the SOCFPGA platform from Steffan Trumtrar, and a
couple of device tree documentation updates/typo fix.

This one does not the GPIO binding patch, as that is pending further
discussion. Also, v3 fixes a rebase artifact and compile tested.

Pawel Moll 974cc7b934 mfd: vexpress: Define the device as MFD cells
This patch - finally, after over 6 months! :-( - addresses
Samuel's request to split the vexpress-sysreg driver into
smaller portions and define the device in a form of MFD
cells:

* LEDs code has been completely removed and replaced with
  "gpio-leds" nodes in the tree (referencing dedicated
  GPIO subnodes in sysreg - bindings documentation updated);
  this also better fits the reality as some variants of the
  motherboard don't have all the LEDs populated

* syscfg bridge code has been extracted into a separate
  driver (placed in drivers/misc for no better place)

* all the ID & MISC registers are defined as sysconf
  making them available for other drivers should they need
  to use them (and also to the user via /sys/kernel/debug/regmap
  which can be helpful in platform debugging)

Pawel Moll 3b9334ac83 mfd: vexpress: Convert custom func API to regmap
Components of the Versatile Express platform (configuration
microcontrollers on motherboard and daughterboards in particular)
talk to each other over a custom configuration bus. They
provide miscellaneous functions (from clock generator control
to energy sensors) which are represented as platform devices
(and Device Tree nodes). The transactions on the bus can
be generated by different "bridges" in the system, some
of which are universal for the whole platform (for the price
of high transfer latencies), others restricted to a subsystem
(but much faster).

Until now drivers for such functions were using custom "func"
API, which is being replaced in this patch by regmap calls.
This required:

* a rework (and move to drivers/bus directory, as suggested
  by Samuel and Arnd) of the config bus core, which is much
  simpler now and uses device model infrastructure (class)
  to keep track of the bridges; non-DT case (soon to be
  retired anyway) is simply covered by a special device
  registration function

* the new config-bus driver also takes over device population,
  so there is no need for special matching table for
  of_platform_populate nor "simple-bus" hack in the arm64
  model dtsi file (relevant bindings documentation has
  been updated); this allows all the vexpress devices
  fit into normal device model, making it possible
  to remove plenty of early inits and other hacks in
  the near future

* adaptation of the syscfg bridge implementation in the
  sysreg driver, again making it much simpler; there is
  a special case of the "energy" function spanning two
  registers, where they should be both defined in the tree
  now, but backward compatibility is maintained in the code

* modification of the relevant drivers:

  * hwmon - just a straight-forward API change
  * power/reset driver - API change
  * regulator - API change plus error handling
    simplification
  * osc clock driver - this one required larger rework
    in order to turn in into a standard platform driver

Names of subdirectories created become names of properties.
Each property contains two attributes: "type" and "data".
The type can be a numeric value 1..7 while data is a blob interpreted
depending on the type specified.
The types are:
1 - unicode string
2 - unicode string with environment variables
3 - binary
4 - little-endian 32-bit
5 - big-endian 32-bit

invocations used for adding the configurations. The configuration is selected
by creating a symbolic link pointing to it from the "os_desc" directory
located at the top of a gadget's directory hierarchy.

One kind of "OS Descriptors" are "Extended Compatibility Descriptors",
which need to be specified per interface. This patch adds interface.<n>
directory in function's configfs directory to represent each interface
defined by the function. Each interface's directory contains two attributes:
"compatible_id" and "sub_compatible_id", which represent 8-byte

Linus Torvalds 200d963bf4 ARM: SoC fixes for 3.15-rc
Seems like we've had more fixes than usual this release cycle, but
 there's nothing in particular that we're doing differently. Perhaps it's
 just one of those cycles where more people are finding more regressions
 (and/or that the latency of when people actually test what's been in
 the tree for a while is catching up so that we get the bug reports now).
 
 The bigger changes here are are for TI and Marvell platforms:
 * Timing changes for GPMC (generic localbus) on OMAP causing some largeish
   DTS deltas.
 * Fixes to window allocation on PCI for mvebu touching drivers/ stuff. Patches
   have acks from subsystem maintainers where needed.
 * A fix from Thomas for a botched DT conversion in drivers/edma.
 
 There's a handful of other fixes for the above platforms as well as sunxi,
 at91, i.MX. I also included a MAINTAINER update for Broadcom, and a trivial
 move of a binding doc.

Shawn Guo 886cda418b ARM: imx6q: add the missing esai_ahb clock
The esai_ahb clock is derived from ahb and used to provide ESAI the
capability of register accessing and FSYS clock source for I2S clocks
dividing.  The gate bits of this esai_ahb clock are shared with the
esai clock -- the baud clock, so we need to call imx_clk_gate2_shared()
for these two clocks.

Thierry Reding 29a1f2333e gpio: Add helpers for optional GPIOs
Introduce gpiod_get_optional() and gpiod_get_index_optional() helpers
that make it easier for drivers to handle optional GPIOs.

Currently in order to handle optional GPIOs, a driver needs to special
case error handling for -ENOENT, such as this:

	gpio = gpiod_get(dev, "foo");
	if (IS_ERR(gpio)) {
		if (PTR_ERR(gpio) != -ENOENT)
			return PTR_ERR(gpio);

		gpio = NULL;
	}

	if (gpio) {
		/* set up GPIO */
	}

With these new helpers the above is reduced to:

	gpio = gpiod_get_optional(dev, "foo");
	if (IS_ERR(gpio))
		return PTR_ERR(gpio);

	if (gpio) {
		/* set up GPIO */
	}

While at it, device-managed variants of these functions are also
provided.

This commit adds the SMP support for Armada 375 and Armada 38x. It
turns out that the SMP logic for both of these SOCs are fairly
similar, the only differences being:

 * A different method to set the secondary CPU boot address

 * An Armada 375 specific workaround needed for the early Z1 stepping,
   added by the following patch.

Other than that, the patch is fairly straightforward and adds the
usual platsmp and headsmp code, defining the smp_operations structure
that is referenced from the DT_MACHINE structures.

Hans de Goede 886129a8ee ACPI / video: change acpi-video brightness_switch_enabled default to 0
acpi-video is unique in that it not only generates brightness up/down
keypresses, but also (sometimes) actively changes the brightness itself.

This presents an inconsistent kernel interface to userspace, basically there
are 2 different scenarios, depending on the laptop model:

 1) On some laptops a brightness up/down keypress means: show a brightness osd
 with the current brightness, iow it is a brightness has changed notification.

 2) Where as on (a lot of) other laptops it means a brightness up/down key was
 pressed, deal with it.

Most of the desktop environments interpret any press as in scenario 2, and
change the brightness up / down as a response to the key events, causing it
to be changed twice, once by acpi-video and once by the DE.

With the new default for video.use_native_backlight we will be moving even
more laptops over to behaving as in scenario 2. Making the remaining laptops
even more of a weird exception. Also note that it is hard to detect scenario
1 properly in userspace, and AFAIK none of the DE-s deals with it.

Therefor this commit changes the default of brightness_switch_enabled to 0
making its behavior consistent with all the other backlight drivers.

Afzal Mohammed 27b7d5f3cc bus: omap_l3_noc: Add AM4372 interconnect error data
Add AM4372 information to handle L3 error.

AM4372 has two clk domains 100f and 200s. Provide flagmux and data
associated with it.

NOTE: Timeout doesn't have STDERRLOG_MAIN register. And per hardware
team, L3 timeout error cannot be cleared the normal way (by setting
bit 31 in STDERRLOG_MAIN), instead it may be required to do system
reset. L3 error handler can't help in such scenarios.

Hence indicate timeout target offset as L3_TARGET_NOT_SUPPORTED as
done for undocumented bits.

Rajendra Nayak 53a848be0a bus: omap_l3_noc: Add DRA7 interconnect error data
DRA7 is distinctly different from OMAP4 in terms of masters and clock
domain organization. There two main clock domains which is divided as
follows:
     <0x44000000 0x1000000> is clk1 and clk2 is the sub clock domain
     <0x45000000 0x1000> is clk3

Add all the data needed to handle L3 error handling on DRA7 devices
and mark clk2 as subdomain and provide a compatible flag for
functionality. Other than the data difference the hardware blocks
involved are essentially the same.

Hans de Goede 36189cc3cd Input: elantech - fix touchpad initialization on Gigabyte U2442
The hw_version 3 Elantech touchpad on the Gigabyte U2442 does not accept
0x0b as initialization value for r10, this stand-alone version of the
driver: http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2

Uses 0x03 which does work, so this means not setting bit 3 of r10 which
sets: "Enable Real H/W Resolution In Absolute mode"

Which will result in half the x and y resolution we get with that bit set,
so simply not setting it everywhere is not a solution. We've been unable to
find a way to identify touchpads where setting the bit will fail, so this
patch uses a dmi based blacklist for this.

Thomas Gleixner cf7eb97911 ARM: common: edma: Fix xbar mapping
This is another great example of trainwreck engineering:

commit 2646a0e529 (ARM: edma: Add EDMA crossbar event mux support)
added support for using EDMA on peripherals which have no direct EDMA
event mapping.

The code compiles and does not explode in your face, but that's it.

1) Reading an u16 array from an u32 device tree array simply does not
   work. Even if the function is named "edma_of_read_u32_to_s16_array".

   It merily calls of_property_read_u16_array. So the resulting 16bit
   array will have every other entry = 0.

2) The DT entry for the xbar registers related to xbar has length 0x10
   instead of the real length: 0xfd0 - 0xf90 = 0x40.

   Not a real problem as it does not cross a page boundary, but
   wrong nevertheless.

3) But none of this matters as the mapping never happens:

   After reading nonsense edma_of_read_u32_to_s16_array() invalidates
   the first array entry pair, so nobody can ever notice the
   braindamage by immediate explosion.

Seems the QA criteria for this code was solely not to explode when
someone adds edma-xbar-event-map entries to the DT. Goal achieved,
congratulations!

Not really helpful if someone wants to use edma on a device which
requires a xbar mapping.

Fix the issues by:

- annotating the device tree entry with "/bits/ 16" as documented in
  the of_property_read_u16_array kernel doc

- make the size of the xbar register mapping correct

- invalidating the end of the array and not the start

This convoluted mess wants to be completely rewritten as there is no
point to keep the xbar_chan array memory and the iomapping of the xbar
regs around forever. Marking the xbar mapped channels as used should
be done right there.

But that's a different issue and this patch is small enough to make it
work and allows a simple backport for stable.

Thomas Petazzoni 0456d3300e memory: mvebu-devbus: add a devbus, keep-config property
Currently, the mvebu-devbus Device Tree binding makes defining the
timing parameters mandatory.

However, in practice, when converting Orion5x platforms to the Device
Tree, we may not necessarily have easy access to the hardware
platforms to fetch those values which were not defined in old-style
board files: all these platforms rely on the bootloader setting the
timing parameters correctly.

In order to facilitate the migration to the Device Tree of this
platform, this commit relaxes the mvebu-devbus Device Tree binding by
introducing a 'devbus,keep-config' boolean property, which, if
defined, will ignore all timing parameters passed in the Device Tree,
and simply rely on the timing values already defined by the
bootloader.

This commit adds support for the Orion5x family of Marvell processors
into the mvebu-devbus driver. It differs from the already supported
Armada 370/XP by:

 * Having a single register (instead of two) for doing all the timing
   configuration.

 * Having a few less timing configuration parameters.

For this reason, a separate compatible string "marvell,orion-devbus"
is introduced.

Lorenzo Pieralisi 82a5619410 clocksource: arch_arm_timer: Fix age-old arch timer C3STOP detection issue
ARM arch timers are tightly coupled with the CPU logic and lose context
on platform implementing HW power management when cores are powered
down at run-time. Marking the arch timers as C3STOP regardless of power
management capabilities causes issues on platforms with no power management,
since in that case the arch timers cannot possibly enter states where the
timer loses context at runtime and therefore can always be used as a high
resolution clockevent device.

In order to fix the C3STOP issue in a way compliant with how real HW
works, this patch adds a boolean property to the arch timer bindings
to define if the arch timer is managed by an always-on power domain.

This power domain is present on all ARM platforms to date, and manages
HW that must not be turned off, whatever the state of other HW
components (eg power controller). On platforms with no power management
capabilities, it is the only power domain present, which encompasses
and manages power supply for all HW components in the system.

If the timer is powered by the always-on power domain, the always-on
property must be present in the bindings which means that the timer cannot
be shutdown at runtime, so it is not a C3STOP clockevent device.
If the timer binding does not contain the always-on property, the timer is
assumed to be power-gateable, hence it must be defined as a C3STOP
clockevent device.

Gregory CLEMENT 0c3acc746d ARM: mvebu: extend the PMSU registers
The initial binding for PMSU was wrong, as it didn't take into account
all the registers from the PMSU and moreover it referred to the CPU
reset registers which are not part of PMSU.

The Power Management Unit Service block also controls the Coherency
Fabric subsystem. These registers are needed for the CPU idle
implementation for the Armada 370/XP, it allows to enter a deep CPU
idle state where the Coherency Fabric and the L2 cache are powered
down.

This commit adds support for a new compatible for the PMSU node which
includes the registers related to the coherency fabric. It also keeps
compatibility with the old compatible string.

Thomas Petazzoni 3f20fb1153 ARM: mvebu: introduce CPU reset code
The Armada 370 and Armada XP have registers that allow to reset the
CPUs, which is particularly useful to take the secondary CPUs out of
reset in the context of the SMP support.

Unfortunately, an implementation mistake was originally made and the
support for these registers was integrated into the PMSU driver, which
is in fact completely unrelated. And it turns out that the Armada 375
has the same CPU reset registers, but does not have the PMSU
registers.

Therefore, this commit creates a small CPU reset driver. All it does
is provide a simple mvebu_cpu_reset_deassert() function that the SMP
support code can call to take secondary CPUs out of reset. As of this
commit, the driver isn't being used, it will be used through changes
in the following commits.

Note that we initially planned to use the 'reset controller'
framework, but it requires the addition of "resets" properties in the
Device Tree, which are causing too many problems if we want to keep
the Device Tree backward compatibility. Moreover, the 'reset
controller' framework is mainly useful when a device driver needs to
request a reset of its device from a separate reset controller. In our
case, the CPU reset handling and the SMP core code are both located in
arch/arm/mach-mvebu/ and are tightly linked together, so there's no
real benefit in going through a separate framework.

Armada 375 SoC, except that it does not have the bug of the Armada 375
coherency unit that requires the XOR based workaround.

This commit therefore extends the Marvell EBU coherency code with a
new compatible string to support the Armada 38x coherency unit.

Thomas Petazzoni 77fa4b9ab0 ARM: mvebu: add Armada 375 support to the coherency code
The Armada 375, like the Armada 370 and Armada XP, has a coherency
unit. However, unlike the coherency unit of 370/XP which does both CPU
and I/O coherency, the one on Armada 735 only does I/O
coherency. Therefore, instead of having two sets of registers (the
first one being used mainly to register each CPU in the coherency
fabric, the second one being used for the I/O coherency barrier), it
has only one set of register (for the I/O coherency barrier).

This commit adds a new "marvell,armada-375-coherency-fabric"
compatible string for this variant of the coherency fabric. The custom
DMA operations, and the way of triggering an I/O barrier is the same
as Armada 370/XP, so the code changes are minimal. However, the
set_cpu_coherent() function is not needed on Armada 375 and will not
work.

Thomas Petazzoni 924d38f404 ARM: mvebu: prepare coherency code to support more SOCs
The code that handles the coherency fabric of Armada 370 and Armada XP
in arch/arm/mach-mvebu/coherency.c made the assumption that there was
only one type of coherency fabric. Unfortunately, it turns out that
upcoming SoCs have a slightly different coherency unit.

In preparation to the introduction of the coherency support for more
SoCs, this commit:

 * Introduces a data associated to the compatible string in the
   compatible string match table, so that the code can differantiate
   the variant of coherency unit being used.

 * Separates the coherency unit initialization code into its own
   function.
