Cleanups for 3.16. Among these are:
- A bunch of misc cleanups for Broadcom platforms, mostly housekeeping
- Enabling Common Clock Framework on the older s3c24xx Samsung chipsets
- Cleanup of the Versatile Express system controller code, moving it to syscon
- Power management cleanups for OMAP platforms
+ a handful of other cleanups across the place

Call pcie_bus_configure_settings() on ARM, like for other platforms.
pcie_bus_configure_settings() makes sure the MPS across the bus is uniform
and provides the ability to tune the MRSS and MPS to higher performance
values. This is particularly important for embedded where there is no
firmware to program these PCIe settings for the OS.

When targetting ARCH_MULTIPLATFORM, we may include support for SoCs with

This patch allows PCI support to be selected for these SoCs by selecting
CONFIG_MIGHT_HAVE_PCI when CONFIG_ARCH_MULTIPLATFORM=y and removes the
individual selections from multi-platform enabled SoCs.

The content of /sys/devices/system/cpu/cpu*/online is still 1 for those
CPUs that the switcher has removed even though the global state in
/sys/devices/system/cpu/online is updated correctly.
It turns out that commit 0902a9044f ("Driver core: Use generic
offline/online for CPU offline/online") has changed the way those files
retrieve their content by relying on on the generic attribute handling
code. The switcher, by calling cpu_down() directly, bypasses this
handling and the attribute value doesn't get updated.
Fix this by calling device_offline()/device_online() instead.

pcibios_penalize_isa_irq() is only implemented by x86 now, and legacy ISA
is not used by some architectures. Make pcibios_penalize_isa_irq() a
__weak function to simplify the code. This removes the need for new

The versatile express changes for 3.16 introduced a number of
build regressions for randconfig kernels by not tracking dependencies
between the components right.
This patch tries to rectify that:
* the mach-vexpress code cannot link without the syscfg driver,
which in turn needs MFD_VEXPRESS_SYSREG
* various drivers call devm_regmap_init_vexpress_config(), which
has to be exported so it can be used by loadable modules
* the configuration bus uses OF DT helper functions that are not
available to platforms disable CONFIG_OF
* The sysreg driver exports GPIOs through gpiolib, which can
be disabled on some platforms.
* The clocksource code cannot be built on platforms that don't
use modern timekeeping but rely on gettimeoffset.

According to the ARM ARM, the behaviour is UNPREDICTABLE if the PC read
from the exception return stack is not half word aligned. See the
pseudo code for ExceptionReturn() and PopStack().
The signal handler's address has the bit 0 set, and setup_return()
directly writes this to regs->ARM_pc. Current hardware happens to
discard this bit, but QEMU's emulation doesn't and this makes processes
crash. Mask out bit 0 before the exception return in order to get
predictable behaviour.

The arm EABI states that unwind opcode 10100nnn means pop register r4-4[4+nnn],aditionally there is a similar unwind opcode: 10101nnn which means the same thing plus popping r14. Those two cases are handled by the unwind_exec_pop_r4_to_rN function which checks whether the 4th bit is set and does r14 popping.
However, up until now it has been checking whether the 8th bit was set (mask & 0x80) instead of the 4th (mask & 0x8), a simple to make typo but this meant that we were always popping r14 even if we had the former opcode.
This patch changes the mask so that the 2 unwind opcodes are being handled correctly.

kernel panic happens during access clocks when the

Samsung fixes for 3.15 from Kukjin Kim:
- Remove g2d_pd and mau_pd nodes on exynos5420.
Since the power domains are linked to the CMU blocks,
kernel panic happens during access clocks when the
power domains are disabled. Now this is a best solution.
- Enable HS-I2C on exynos5 by default
MMC partition cannot be mounted for RFS without the
enabling HS-I2C because regulators for MMC power are
connected to HS-I2C bus.
- Disable MDMA1 node on exynos5420
When MDMA1 runs in secure mode it makes kernel fault,
so need to disalbe it on exynos5420 by default instead
of each board.
- Fix the secondary CPU boot for exynos4212

This series reworks VE's platform configuration infrastructure by:
- making it possible to instantiate selected devices from the
Device Tree, prior to massive population,
- converting custom "func" API into standard "regmap",
- splitting the existing MFD driver into smaller ones and placing
them into relevant directories.
The common clock framework driver can now be selected individually
(mostly for arm64 sake, where some of them are not used at all).
It also simplifies the machine code, by:
- moving the shed clock info clocksource driver,
- simplifying SMP operations to base them entirely of the DT data,
- moving platform ID checks into relevant driver.

On OMAP4 panda board, there have been several bug reports about boot
hang and lock-ups with CPU_IDLE enabled. The root cause of the issue
is missing interrupts while in idle state. Commit cb7094e8 {cpuidle / omap4 :
use CPUIDLE_FLAG_TIMER_STOP flag} moved the broadcast notifiers to common
code for right reasons but on OMAP4 which suffers from a nasty ROM code
bug with GIC, commit ff999b8a {ARM: OMAP4460: Workaround for ROM bug ..},
we loose interrupts which leads to issues like lock-up, hangs etc.
Patch reverts commit cb7094 {cpuidle / omap4 : use CPUIDLE_FLAG_TIMER_STOP
flag} and 54769d6 {cpuidle: OMAP4: remove timer broadcast initialization} to
avoid the issue. With this change, OMAP4 panda boards, the mentioned
issues are getting fixed. We no longer loose interrupts which was the cause
of the regression.
Fixes: cb7094e8 (cpuidle / omap4 : use CPUIDLE_FLAG_TIMER_STOP flag)
Fixes: ff999b8a (cpuidle: OMAP4: remove timer broadcast initialization)
