Theodore Ts'o 775f4b297b random: make 'add_interrupt_randomness()' do something sane
We've been moving away from add_interrupt_randomness() for various
reasons: it's too expensive to do on every interrupt, and flooding the
CPU with interrupts could theoretically cause bogus floods of entropy
from a somewhat externally controllable source.

This solves both problems by limiting the actual randomness addition
to just once a second or after 64 interrupts, whicever comes first.
During that time, the interrupt cycle data is buffered up in a per-cpu
pool.  Also, we make sure the the nonblocking pool used by urandom is
initialized before we start feeding the normal input pool.  This
assures that /dev/urandom is returning unpredictable data as soon as
possible.

(Based on an original patch by Linus, but significantly modified by
tytso.)

NeilBrown 17ffba6ad2 mfd: Move twl-core device_init_wakeup to after platform_device_add
device_init_wakeup uses the dev_name() of the device to set the
name of the wakeup_source which appears in
/sys/kernel/debug/wakeup_sources.

For a platform device, that name is not set until platform_device_add
calls dev_set_name.

So the call to device_init_wakeup() must be after the call to
platform_device_add().
Making this change causes correct names to appear in the
wakeup_sources file.

88PM800 and 88PM805 are two discrete chips used for power management.
Hardware designer can use them together or only one of them according
to requirement.

88pm80x.c provides common i2c driver handling for both 800 and
805, such as i2c_driver init, regmap init, read/write api etc.

88pm800.c handles specifically for 800, such as chip init, irq
init/handle, mfd device register, including rtc, onkey, regulator(
to be add later) etc. besides that, 800 has three i2c device, one
regular i2c client, two other i2c dummy for gpadc and power purpose.

88pm805.c handles specifically for 805, such as chip init, irq
init/handle, mfd device register, including codec, headset/mic detect
etc.

Russ Dill c05995c3d7 mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix issues.
'ARM: OMAP3: USB: Fix the EHCI ULPI PHY reset issue' (1fcb57d0) fixes
an issue where the ULPI PHYs were not held in reset while initializing
the EHCI controller. However, it also changes behavior in
omap-usb-host.c omap_usbhs_init by releasing reset while the
configuration in that function was done.

This change caused a regression on BB-xM where USB would not function
if 'usb start' had been run from u-boot before booting. A change was
made to release reset a little bit earlier which fixed the issue on
BB-xM and did not cause any regressions on 3430 sdp, the board for
which the fix was originally made.

This new fix, 'USB: EHCI: OMAP: Finish ehci omap phy reset cycle
before adding hcd.', (3aa2ae74) caused a regression on OMAP5.

The original fix to hold the EHCI controller in reset during
initialization was correct, however it appears that changing
omap_usbhs_init to not hold the PHYs in reset during it's
configuration was incorrect. This patch first reverts both fixes, and
then changes ehci_hcd_omap_probe in ehci-omap.c to hold the PHYs in
reset as the original patch had done. It also is sure to incorporate
the _cansleep change that has been made in the meantime.

I've tested this on Beagleboard xM, I'd really like to get an ack from
the 3430 sdp and OMAP5 guys before getting this merged.

v3 - Brown paper bag its too early in the morning actually run
     git commit amend fix

Philippe Rétornaz ada72d0a93 mfd: mc13xxx workaround SPI hardware bug on i.Mx
The MC13xxx PMIC is mainly used on i.Mx SoC. On those SoC the SPI
hardware will deassert CS line as soon as the SPI FIFO is empty.
The MC13xxx hardware is very sensitive to CS line change as it
corrupts the transfer if CS is deasserted in the middle of a register
read or write.
It is not possible to use the CS line as a GPIO on some SoC, so we
need to workaround this by implementing a single SPI transfer to
access the PMIC.

Lee Jones 3a8e39c9f4 ARM: ux500: Register the AB8500 from DB8500 MFD
As the AB8500 is a subordinate MFD device to the DB8500-PRCMU,
for consistency and a better 1:1 depiction of how the hardware
is laid out, it is a good idea to register it in the same way
as we do for the other MFD child devices. In order for us to do
this successfully we have to pass AB8500's platform data when
registering the DB8500-PRCMU from platform code.

Also solves this issue:

Add flag to platform data to enable external 32-kHz crystal oscillator

The tps6591x can use either an internal 32-kHz RC oscillator or an

The default setting depends on the selected boot mode. In boot mode 00
the internal RC oscillator is used at power-on, but the external crystal
oscillator (or square wave) can be enabled by clearing the ck32k_ctrl
flag in the device control register.

Note that there is no way to switch from the external crystal oscillator

Russ Dill 2761a63945 mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix issues.
'ARM: OMAP3: USB: Fix the EHCI ULPI PHY reset issue' (1fcb57d0) fixes
an issue where the ULPI PHYs were not held in reset while initializing
the EHCI controller. However, it also changes behavior in
omap-usb-host.c omap_usbhs_init by releasing reset while the
configuration in that function was done.

This change caused a regression on BB-xM where USB would not function
if 'usb start' had been run from u-boot before booting. A change was
made to release reset a little bit earlier which fixed the issue on
BB-xM and did not cause any regressions on 3430 sdp, the board for
which the fix was originally made.

This new fix, 'USB: EHCI: OMAP: Finish ehci omap phy reset cycle
before adding hcd.', (3aa2ae74) caused a regression on OMAP5.

The original fix to hold the EHCI controller in reset during
initialization was correct, however it appears that changing
omap_usbhs_init to not hold the PHYs in reset during it's
configuration was incorrect. This patch first reverts both fixes, and
then changes ehci_hcd_omap_probe in ehci-omap.c to hold the PHYs in
reset as the original patch had done. It also is sure to incorporate
the _cansleep change that has been made in the meantime.

I've tested this on Beagleboard xM, I'd really like to get an ack from
the 3430 sdp and OMAP5 guys before getting this merged.

v3 - Brown paper bag its too early in the morning actually run

Lee Jones c94bb233a9 mfd: Make MFD core code Device Tree and IRQ domain aware
During Device Tree enablement of the ab8500 and db8500-prcmu drivers,
a decision was made to omit registration through the MFD API and use
Device Tree directly. However, because MFD devices have a different
address space and the ab8500 and db8500 both use I2C to communicate,
this causes issues with address translation during execution of
of_platform_populate(). So the solution is to make the MFD core aware
of Device Tree and have it assign the correct node pointers instead.

To make this work the MFD core also needs to be awere of IRQ domains,
as Device Tree insists on IRQ domain compatibility. So, instead of
providing an irq-base via platform code, in the DT case we simply
look up the IRQ domain and map to the correct virtual IRQ.

The MC13xxx PMIC is mainly used on i.Mx SoC. On those SoC the SPI
hardware will deassert CS line as soon as the SPI FIFO is empty.
The MC13xxx hardware is very sensitive to CS line change as it
corrupts the transfer if CS is deasserted in the middle of a register
read or write.
It is not possible to use the CS line as a GPIO on some SoC, so we
need to workaround this by implementing a single SPI transfer to
access the PMIC.

Also, bits_per_word should not be set as the regmap spi implementation
uses a 8bits transfert granularity.

Jonghwa Lee dae8a969d5 mfd: Add Maxim 77686 driver
This patch is device driver for MAX77686 chip.
MAX77686 is PMIC and includes regulator and rtc on it.
This driver is core of MAX77686 chip, so provides common support for
accessing on-chip devices. It uses irq_domain to manage irq and regmap
to read/write data to its register with i2c bus.

Several forthcoming Wolfson devices are based on a common platform
known as Arizona allowing a great deal of reuse of driver code. This
patch adds support for the interrupt controller on Arizona class devices.
Since there are two interrupt domains in the device which share a single
/IRQ pin by default we use two regmap IRQ domains with a trivial demux
interrupt domain used to distribute the interrupts to the two devices.
The devices do support multiple interrupt signals, future work will enable
support for using this feature to avoid the demux.

Several forthcoming Wolfson devices are based on a common platform
known as Arizona allowing a great deal of reuse of driver code. This
patch adds core support for these devices.

In order to handle systems which do not use the generic clock API a
simple wrapper for the 32kHz clock domain in the devices is provided.
Once the generic clock API is widely available this code will be moved
over to use that.

For simplicity some WM5102 specific code is included in the core driver,
the effort involved in splitting the device out isn't worth it.

Linus Torvalds 2e341ca686 Sound updates for 3.5-rc1
This is the first big chunk for 3.5 merges of sound stuff.
 There are a few big changes in different areas.  First off, the
 streaming logic of USB-audio endpoints has been largely rewritten
 for the better support of "implicit feedback".  If anything about USB
 got broken, this change has to be checked.
 
 For HD-audio, the resume procedure was changed; instead of delaying
 the resume of the hardware until the first use, now waking up immediately
 at resume.  This is for buggy BIOS.
 
 For ASoC, dynamic PCM support and the improved support for digital links
 between off-SoC devices are major framework changes.
 
 Some highlights are below:
 
 * HD-audio
 - Avoid the accesses of invalid pin-control bits that may stall the codec
 - V-ref setup cleanups
 - Fix the races in power-saving code
 - Fix the races in codec cache hashes and connection lists
 - Split some common codes for BIOS auto-parser to hda_auto_parser.c
 - Changed the PM resume code to wake up immediately for buggy BIOS
 - Creative SoundCore3D support
 - Add Conexant CX20751/2/3/4 codec support
 
 * ASoC
 - Dynamic PCM support, allowing support for SoCs with internal routing
   through components with tight sequencing and formatting constraints
   within their internal paths or where there are multiple components
   connected with CPU managed DMA controllers inside the SoC.
 - Greatly improved support for direct digital links between off-SoC
   devices, providing a much simpler way of connecting things like digital
   basebands to CODECs.
 - Much more fine grained and robust locking, cleaning up some of the
   confusion that crept in with multi-component.
 - CPU support for nVidia Tegra 30 I2S and audio hub controllers and
   ST-Ericsson MSP I2S controolers
 - New CODEC drivers for Cirrus CS42L52, LAPIS Semiconductor ML26124, Texas
   Instruments LM49453.
 - Some regmap changes needed by the Tegra I2S driver.
 - mc13783 audio support.
 
 * Misc
 - Rewrite with module_pci_driver()
 - Xonar DGX support for snd-oxygen
 - Improvement of packet handling in snd-firewire driver
 - New USB-endpoint streaming logic
 - Enhanced M-audio FTU quirks and relevant cleanups
 - Increment the support of OSS devices to 256
 - snd-aloop accuracy improvement
 
 There are a few more pending changes for 3.5, but they will be
 sent slightly later as partly depending on the changes of DRM.

Problem:
When CONFIG_AB8500_CORE is set, building ab8500-core.c and
!(CONFIG_UX500_SOC_DB8500 | CONFIG_MFD_DB8500_PRCMU), both db8500-prcmu.h
and dbx500-prcmu.h take it upon themselves to _both_ create 'return 0'
inline functions for the following:

prcmu_abb_read()
prcmu_abb_write()
prcmu_config_clkout()
prcmu_ac_wake_req()
prcmu_ac_sleep_req()

Solution:
Depend on MFD_DB8500_PRCMU, which in turn depends on UX500_SOC_DB8500.

Linus Torvalds 9bc747bea5 arm-soc: First batch of cleanups
These cleanups are basically all over the place. The idea is to collect
 changes with minimal impact but large number of changes so we can avoid
 them from distracting in the diffstat in the other series.
 
 A significant number of lines get removed here, in particular because
 the ixp2000 and ixp23xx platforms get removed. These have never been
 extremely popular and have fallen into disuse over time with no active
 maintainer taking care of them. The u5500 soc never made it into a
 product, so we are removing it from the ux500 platform.
 
 Many good cleanups also went into the at91 and omap platforms, as has
 been the case for a number of releases.

Mark Brown cd99758ba3 mfd: Convert wm831x to irq_domain
The modern idiom is to use irq_domain to allocate interrupts. This is
useful partly to allow further infrastructure to be based on the domains
and partly because it makes it much easier to allocate virtual interrupts
to devices as we don't need to allocate a contiguous range of interrupt
numbers.

Convert the wm831x driver over to this infrastructure, using a legacy
IRQ mapping if an irq_base is specified in platform data and otherwise
using a linear mapping, always registering the interrupts even if they
won't ever be used. Only boards which need to use the GPIOs as
interrupts should need to use an irq_base.

This means that we can't use the MFD irq_base management since the
unless we're using an explicit irq_base from platform data we can't rely
on a linear mapping of interrupts.  Instead we need to map things via
the irq_domain - provide a conveniencem function wm831x_irq() to save a
small amount of typing when doing so. Looking at this I couldn't clearly
see anything the MFD core could do to make this nicer.

Since we're not supporting device tree yet there's no meaningful
advantage if we don't do this conversion in one, the fact that the
interrupt resources are used for repeated IP blocks makes accessor
functions for the irq_domain more trouble to do than they're worth.

This gets us up to date with the recommended current kernel infrastructure
and should transparently give us device tree interrupt bindings for any
devices using the framework. If an explicit IRQ mapping is passed in then
a legacy interrupt range is created, otherwise a simple linear mapping is
used. Previously a mapping was mandatory so existing drivers should not
be affected.

A function regmap_irq_get_virq() is provided to allow drivers to map
individual IRQs which should be used in preference to the existing
regmap_irq_chip_get_base() which is only valid if a legacy IRQ range is
provided.

Mark Brown ce7e4e1122 mfd: Fix wm831x register range passing for recent ARM updates
The removal of mach/io.h from most ARM platforms also set the range of
valid IO ports to be empty for most platforms when previously any 32
bit integer had been valid. This makes it impossible to add IO resources
as the added range is smaller than that of the root resource for IO ports.

Since we're not really using IO memory at all fix this by defining our
own root resource outside the normal tree and make that the parent of
all IO resources. This also ensures we won't conflict with read IO ports
if we ever run on a platform which happens to use them.

former was unannotated. Since these functions can only be called during
device init make them both __devinit, and while we're at it also annotate
tps65910_i2c_remove() __devexit for symmetry.

Rickard Andersson 6ef9418c9e mfd: Add parameter to disable ab8500 battery management
This patch makes it possible to disable battery management
via a module boot parameter. When 'ab8500-core.no_bm=1' then
ab8500_btemp, ab8500_chargalg, ab8500_charger and ab8500_fg will
not be probed. This boot parameter is used for scripted testing
of the system.

Extra debugging aids are added to mc13xxx_reg_rmw.

(The irq member of the mc13xxx struct is no longer redundant, it's used
