Linus Torvalds eb3d3ec567 Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into next
Pull ARM updates from Russell King:

 - Major clean-up of the L2 cache support code.  The existing mess was
   becoming rather unmaintainable through all the additions that others
   have done over time.  This turns it into a much nicer structure, and
   implements a few performance improvements as well.

 - Clean up some of the CP15 control register tweaks for alignment
   support, moving some code and data into alignment.c

 - DMA properties for ARM, from Santosh and reviewed by DT people.  This
   adds DT properties to specify bus translations we can't discover
   automatically, and to indicate whether devices are coherent.

 - Hibernation support for ARM

 - Make ftrace work with read-only text in modules

 - add suspend support for PJ4B CPUs

 - rework interrupt masking for undefined instruction handling, which
   allows us to enable interrupts earlier in the handling of these
   exceptions.

 - support for big endian page tables

 - fix stacktrace support to exclude stacktrace functions from the
   trace, and add save_stack_trace_regs() implementation so that kprobes
   can record stack traces.

 - Add support for the Cortex-A17 CPU.

 - Remove last vestiges of ARM710 support.

 - Removal of ARM "meminfo" structure, finally converting us solely to
   memblock to handle the early memory initialisation.

Linus Torvalds d27050641e DeviceTree for 3.16:
- Another round of clean-up of FDT related code in architecture code.
   This removes knowledge of internal FDT details from most architectures
   except powerpc.
 - Conversion of kernel's custom FDT parsing code to use libfdt.
 - DT based initialization for generic serial earlycon. The introduction
   of generic serial earlycon support went in thru tty tree.
 - Improve the platform device naming for DT probed devices to ensure
   unique naming and use parent names instead of a global index.
 - Fix a race condition in of_update_property.
 - Unify the various linker section OF match tables and fix several
   function prototype errors.
 - Update platform_get_irq_byname to work in deferred probe cases.
 - 2 binding doc updates

Linus Torvalds 825f4e0271 ARM: SoC updates for 3.16 (part 1)
A quite large set of SoC updates this cycle. In no particular order:
 
 - Multi-cluster power management for Samsung Exynos, adding support for
   big.LITTLE CPU switching on EXYNOS5
 - SMP support for Marvell Armada 375 and 38x
 - SMP rework on Allwinner A31
 - Xilinx Zynq support for SOC_BUS, big endian
 - Marvell orion5x platform cleanup, modernizing the implementation and
   moving to DT.
 - _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
   that their platform can be enabled in the same kernel binary as most
   of the other v7 platforms in the tree. \o/ The work isn't quite complete,
   there's some driver fixes still needed, but the basics now work.
 
 New SoC support added:
 - Freescale i.MX6SX
 - LSI Axxia AXM55xx SoCs
 - Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800
 - STi STIH407
 
 Plus a large set of various smaller updates for different platforms. I'm
 probably missing some important one here.

Shawn Guo f9f28cdf21 ARM: imx: add shared gate clock support
It's quite common on i.MX that one gate bit controls the gating of
multiple clocks, i.e. this is a shared gate.  The patch adds the
function imx_clk_gate2_shared() for such case.  The clocks controlled
by the same gate bits should call this function with a pointer to a
single share count variable, so that the gate bits will only be
operated on the first enabling and the last disabling of these shared
gate clocks.

Thanks to Gerhard Sittig <gsi@denx.de> for this idea.

Shawn Guo 94b5c02882 ARM: imx: lock is always valid for clk_gate2
The imx specific clk_gate2 always has a valid lock with the clock.  So
the validation on gate->lock is not really needed.  Remove it.

Shawn Guo 54ee1471f8 ARM: imx: define struct clk_gate2 on our own
The imx clk-gate2 driver implements an i.MX specific gate clock, which
has two bits controlling the gate states.  While this is a completely
separate gate driver from the common clk-gate one, it reuses the common
clk_gate structure.  Such reusing makes the extending of clk_gate2
clumsy.  Let's define struct clk_gate2 on our own to make the driver
independent of the common clk-gate one, and ease the clk_gate2 extending
at a later time.
