0d713cf1a6 ARM: EXYNOS: Fix build with PM_SLEEP=n and ARM_EXYNOS_CPUIDLE=y
Fix building of exynos_defconfig with CONFIG_PM_SLEEP disabled and
CONFIG_ARM_EXYNOS_CPUIDLE enabled by:

* adding EXYNOS_CPU_SUSPEND config option
* always building sleep.o
* building pm.o if EXYNOS_CPU_SUSPEND is enabled
* moving suspend specific code from pm.c to suspend.c
* enabling pm-common.o build also for EXYNOS_CPU_SUSPEND option

[ Please note that there are no changes in the code moved from pm.c
  to suspend.c except making few functions non-static and cleaning
  up includes. ]

Also while at it update Copyright dates.

The build error messages:
drivers/built-in.o: In function `exynos_enter_core0_aftr':
/home/bzolnier/linux/drivers/cpuidle/cpuidle-exynos.c:36: undefined reference to `cpu_suspend'
arch/arm/mach-exynos/built-in.o:(.data+0x74): undefined reference to `exynos_enter_aftr'
make: *** [vmlinux] Error 1

This patch has been tested on Exynos4210 based Origen board.

2b9d9c321b ARM: EXYNOS: Add support for firmware-assisted suspend/resume
On a numer of Exynos-based boards Linux kernel is running in non-secure
mode under a secure firmware. This means that certain operations need to
be handled in special way, with firmware assistance. System-wide
suspend/resume is an example of such operations.

This patch adds support for firmware-assisted suspend/resume by
leveraging recently introduced suspend and resume firmware operations
and modifying existing suspend/resume paths to account for presence of
secure firmware.

ac84eb47cc kbuild: remove unnecessary variable initializaions
Clearing obj-y, obj-m, obj-n, obj- in each Makefile is
a useless habit.

They are non-exported variables; therefore they are always empty
whenever descending into each subdirectory.
(Moreorver, obj-y and obj-m are also set to empty at the beginning
of scripts/Makefile.build)

a727eaf64f ARM: SoC driver changes
SoC-near driver changes that we're merging through our tree. Mostly
 because they depend on other changes we have staged, but in some cases
 because the driver maintainers preferred that we did it this way.
 
 This contains a largeish cleanup series of the omap_l3_noc bus driver,
 cpuidle rework for Exynos, some reset driver conversions and a long
 branch of TI EDMA fixes and cleanups, with more to come next release.
 
 The TI EDMA cleanups is a shared branch with the dmaengine tree, with
 a handful of Davinci-specific fixes on top.
 
 After discussion at last year's KS (and some more on the mailing lists),
 we are here adding a drivers/soc directory. The purpose of this is
 to keep per-vendor shared code that's needed by different drivers but
 that doesn't fit into the MFD (nor drivers/platform) model. We expect
 to keep merging contents for this hierarchy through arm-soc so we can
 keep an eye on what the vendors keep adding here and not making it a
 free-for-all to shove in crazy stuff.

 Note that this requires tags/samsung-cleanup and tags/samsung-clk-2
 because of mostly migration exynos specific macros into mach-exynos
 and exynos related Kconfig entries.
 
 One more merge conflict happens in arch/arm/Kconfig for ARCH_EXYNOS
 due to SRAM stuff, even though tried to sort them out. Since just
 resolving it would be better I think, please remove ARCH_EXYNOS in
 arch/arm/Kconfig when merge conflict happens.

d710aa3187 ARM: EXYNOS: Stop using legacy Samsung PM code
Since Exynos SoCs does not follow most of the semantics of older SoCs
when configuring the system to enter sleep, there is no reason to rely
on the legacy Samsung PM core anymore.

This patch adds local Exynos suspend ops and removes all the code left
unnecessary. As a side effect, suspend support on Exynos becomes
multiplatform-friendly.

Moreover the kernel image won't even link if neither CONFIG_MACH_EXYNOS4_DT

bca28f8f6b ARM: EXYNOS: Add support for Exynos secure firmware
Some Exynos-based boards contain secure firmware and must use firmware
operations to set up some hardware.

This patch adds firmware operations for Exynos secure firmware and a way
for board code and device tree to specify that they must be used.

Example of use:

In board code:

  ...MACHINE_START(...)
          /* ... */
          .init_early   = exynos_firmware_init,
          /* ... */
  MACHINE_END

In device tree:

  / {
          /* ... */

          firmware@0203F000 {
                  compatible = "samsung,secure-firmware";
                  reg = <0x0203F000 0x1000>;

db5b0ae007 ARM: arm-soc: device tree conversions and enablement
Continued device tree conversion and enablement across a number of
 platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other
 smaller series as well.
 
 ux500 has seen continued conversion for platforms. Several platforms have
 seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra
 is adding data for new devices/drivers, and Exynos has a bunch of new
 bindings and devices added as well.
 
 So, pretty much the same progression in the right direction as the last
 few releases.

This contains the bulk of new SoC development for this merge window.
 
 Two new platforms have been added, the sunxi platforms (Allwinner A1x
 SoCs) by Maxime Ripard, and a generic Broadcom platform for a new
 series of ARMv7 platforms from them, where the hope is that we can
 keep the platform code generic enough to have them all share one mach
 directory. The new Broadcom platform is contributed by Christian Daudt.
 
 Highbank has grown support for Calxeda's next generation of hardware,
 ECX-2000.
 
 clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also
 taken on maintainership of the platform.
 
 Beyond this there has been a bunch of work from a number of people on
 converting more platforms to IRQ domains, pinctrl conversion, cleanup
 and general feature enablement across most of the active platforms.

bca10b906f ARM: EXYNOS: Change System MMU platform device definitions
Handling System MMUs with an identifier is not flexible to manage
System MMU platform devices because of the following reasons:
1. A device driver which needs to handle System MMU must know the ID.
2. A System MMU may not present in some implementations of Exynos family.
3. Handling System MMU with IOMMU API does not require an ID.

This patch is the result of removing ID of System MMUs.
Instead, a device driver that needs to handle its System MMU must
use IOMMU API while its descriptor of platform device is given.

This patch also includes the following enhancements:
- A System MMU device becomes a child if its power domain device.
- clkdev

Quite a bit of code gets removed, and some stuff moved around, mostly
 the old samsung s3c24xx stuff. There should be no functional changes
 in this series otherwise. Some cleanups have dependencies on other
 arm-soc branches and will be sent in the second round.

b3e68fb17a ARM: EXYNOS: add support device tree enabled board file for EXYNOS5
This patch adds a new EXYNOS5 compatible device tree enabled board
When using this, a corresponding device tree blob which describes the
board's properties should be supplied at boot time to the kernel.

In all of Samsung platform, the setup-i2c0.c file for I2C channel 0
is always compiled. So when supporting new SoC,it should be updated
for it. Since EXYNOS5 GPIO will be supported after this, there is no
setup gpio in there now. It will be implemented with that, of course.

ce9c00eea1 ARM: EXYNOS: replace clock.c for other new EXYNOS SoCs
This patch changes the name of clock.c to clock-exynos4.c for other
EXYNOS series such as EXYNOS5. And since the header file of clock
is used only in arch/arm/mach-exynos, moves it in the local directory.

91cfbd4ee0 ARM: EXYNOS: Hook up power domains to generic power domain infrastructure
Add support for generic power domain for Exynos4 platforms and remove the
Samsung specific power domain control for Exynos4.

The generic power domain infrastructure is used to control the power domains
available on Exynos4. For non-dt platforms, the power domains are statically
instantiated. For dt platforms, the power domain nodes found in the device
tree are instantiated.
