Merge tag 'socfpga-clk-update-for-v3.16' of git://git.rocketboards.org/linux-socfpga-next into clk-next-socfpga
Adds support getting the divider registers for the MAIN PLL that was once
thought to be hidden.
With the addition of clock-indices, we need to change the renesas
clock implementation to use these instead of the local definition
of "renesas,clock-indices".
Since this will break booting with older device trees, we add a
simple auto-detection of which properties are present.

Rather than "manually" setting up each CCU's clock entries at run
time, define a flexible array of generic Kona clock structures
within the CCU structure itself. Each of these entries contains
generic kona clock information (like its CCU pointer and clock
framework initialization data). Each also has a pointer to a
structure contianing clock type-dependent initialization data
(like register definitions).
Since we'll iterate over these arrays we need to be sure they have
slots for all potential clock index values. (E.g. for the root CCU
we must have at least BCM281XX_ROOT_CCU_CLOCK_COUNT slots.) To
ensure this we always define an extra entry and fill it using the
special initializer LAST_KONA_CLK.
Just about everything we need to know about a clock can be defined
statically. As a result, kona_clk_setup() can be changed to take
just a kona_clk structure as its argument, and peri_clk_setup() can
be simplified. With the information pre-defined we are also able
to handle most clock setup genericially. We can do away with the
CCU-specific callback functions that previously were needed to set
up the entries in CCU's clock array.
Move the definition of the ccu_data structure down in "clk-kona.h"
to avoid a forward dependency.

We know up front how many CCU's we'll support, so there's no need to
allocate their data structures dynamically. Define a macro
KONA_CCU_COMMON() to simplify the initialization of many of the
fields in a ccu_data structure. Pass the address of a statically
defined CCU structure to kona_dt_ccu_setup() rather than having that
function allocate one.
We also know at build time how many clocks a given CCU will provide,
though the number of of them for each CCU is different. Record the
number of clocks we need in the CCU's clk_onecell_data struct
(which is used when we register the CCU with the common clock code
as a clock provider). Rename that struct field "clk_data" (because
"data" alone gets a little confusing).
Use the known clock count to move the allocation of each CCU's
clocks array into ccu_clks_setup() rather than having each CCU's
setup callback function do it.
(The real motivation behind all of this is that we'll be doing some
static initialization of some additional CCU-specific data soon.)

As I developed the bcm281xx clock code I understood there were
restrictions on device tree "compatible" strings names, and as a
result "bcm11351" was used in places despite the part family being
more properly called "bcm281xx". This can be a little confusing.
In some cases I went to far and things using "bcm11351" when that
was not necessary.
This patch remedies this. It renames the symbol used to define the
"compatible" string (but not its value) so it uses "BCM281XX".
Similarly, the name names provided to the CLK_OF_DECLARE() macro
are changed, hoping to minimize the number of places that the
confusing "11351" string is used.

clk: socfpga: clock fix for v3.15
Currently on 3.15-rc1, the SOCFPGA platform is unable to boot. This patch
fixes the issue and allows the platform to boot.
commit [1771b10d6 clk: respect the clock dependencies in of_clk_init]
exposed a flaw in the socfpga clock driver and prevents the platform
from booting on 3.15-rc1.
Because the "altr,clk-mgr" is not really a clock, it should not be using
CLK_OF_DECLARE, instead we should be mapping the clk-mgr's base address
one of the functional clock init function. Use the socfpga_pll_init function
to map the clk_mgr_base_addr as this clock should always be initialized first.

Pull irq fixes from Thomas Gleixner:
"A slighlty large fix for a subtle issue in the CPU hotplug code of
certain ARM SoCs, where the not yet online cpu needs to setup the cpu
local timer and needs to set the interrupt affinity to itself.
Setting interrupt affinity to a not online cpu is prohibited and
therefor the timer interrupt ends up on the wrong cpu, which leads to
nasty complications.
The SoC folks tried to hack around that in the SoC code in some more
than nasty ways. The proper solution is to have a way to enforce the
affinity setting to a not online cpu. The core patch to the genirq
code provides that facility and the follow up patches make use of it
in the GIC interrupt controller and the exynos timer driver.
The change to the core code has no implications to existing users,
except for the rename of the locked function and therefor the
necessary fixup in mips/cavium. Aside of that, no runtime impact is
possible, as none of the existing interrupt chips implements anything
which depends on the force argument of the irq_set_affinity()
callback"

Pull ACPI and power management fixes from Rafael Wysocki:
"These include a fix for a recent ACPI regression related to device
notifications, intel_idle fix related to IvyTown support, fix for a
buffer size issue in ACPICA, PM core fix related to the "freeze" sleep
state, four fixes for various types of breakage in cpufreq drivers, a
PNP workaround for a wrong memory region size in ACPI tables, and a
fix and cleanup for the ACPI tools Makefile.
Specifics:
- Fix for broken ACPI notifications on some systems caused by a
recent ACPI hotplug commit that blocked the propagation of unknown
type notifications to device drivers inadvertently.
- intel_idle fix to make the IvyTown C-states handling (added
recently) work as intended which now is broken due to missing
braces. From Christoph Jaeger.
- ACPICA fix to make it allocate buffers of the right sizes for the
Generic Serial Bus operation region access. From Lv Zheng.
- PM core fix unblocking cpuidle before entering the "freeze" sleep
state which causes that state to be able to actually save more
energy than runtime idle.
- Configuration and build fixes for the highbank and powernv cpufreq
drivers from Kefeng Wang and Srivatsa S Bhat.
- Coccinelle warning fix related to error pointers for the unicore32
cpufreq driver from Duan Jiong.
- Integer overflow fix for the ppc-corenet cpufreq driver from Geert
Uytterhoeven.
- Workaround for BIOSes that don't report the entire Intel MCH area
in their ACPI tables from Bjorn Helgaas.
- ACPI tools Makefile fix and cleanup from Thomas Renninger"

tools/power/acpi: Minor bugfixes
This commit adds a core clock driver for the Orion5x SoC, with support
for the tclk, the CPU frequency and the DDR frequency. All the details
about the Sample-At-Reset register were extracted from the U-Boot
sources for Orion5x.
Note that Orion5x does not have gatable clocks, so this core clock
driver is sufficient to support clocking on Orion5x platforms.
