Pankaj Dubey 2e94ac4289 ARM: EXYNOS: Refactored code for using PMU address via DT
Under "arm/mach-exynos" many files are using PMU register offsets.
Since we have added support for accessing PMU base address via DT,
now we can remove PMU mapping from exynosX_iodesc. Let's convert
all these access using iomapped address.
This will help us in removing static mapping of PMU base address
as well as help in reducing dependency over machine header files.
Thus helping for migration of PMU implementation from machine to
driver folder which can be reused for ARM64 based SoC.

Also as we have removed static mappings from "regs-pmu.h" it does
not need map.h anymore. But "platsmp.c" needed this and till now it
got included indirectly. So lets move header inclusion of
"mach/map.h" from "regs-pmu.h" to "platsmp.c".

Pankaj Dubey 4552386a3e ARM: EXYNOS: Remove file path from comment section
Many files under "arm/mach-exynos" are having file path in file
comment section which is invalid now.
So for better code maintainability let's remove them.

Sachin Kamat b3205dea8f ARM: EXYNOS: Map SYSRAM through generic DT bindings
Instead of hardcoding the SYSRAM details for each SoC,
pass this information through device tree (DT) and make
the code SoC agnostic. Generic DT SRAM bindings are
used for achieving this.

Linus Torvalds 2bf73dd61a ARM: SoC: late cleanups
These could not be part of the first cleanup branch, because they either
 came too late in the cycle, or they have dependencies on other branches.
 Important changes are:
 
 * The integrator platform is almost multiplatform capable after
   some reorganization (Linus Walleij)
 * Minor cleanups on Zynq (Michal Simek)
 * Lots of changes for Exynos and other Samsung platforms, including
   further preparations for multiplatform support and the clocks bindings
   are rearranged.

Arnd Bergmann 2c793fa349 Samsung PM related 2nd updates for v3.15
From Tomasz Figa <t.figa@samsung.com>:
 Current Samsung PM code is heavily unprepared for multiplatform
 systems. The design implies accessing functions and global
 variables defined in particular mach- subdirectory from common
 code in plat-, which is not allowed when building ARCH_MULTIPLATFORM.
 In addition there is a lot of forced code unification, which makes
 common function handle any possible quirks of all supported SoCs.
 In the end this design turned out to not work too well, ending with
 a lot of empty functions exported from mach-, just because code in
 common pm.c calls them. Moreover, recent trend of moving lower level
 suspend/resume code to proper drivers, like pinctrl or clk, made a
 lot of code there redundant, especially on DT-only platforms like
 Exynos.
 
 Note that this branch is based on previous tags/samsung-pm-1 and merge
 tags/samsung-cleanup-2 because of fix build error from recent changes
 of <linux/serial_s3c.h>

On EXYNOS5440 there is DRAM on the 36-bit address range. Hence
this patch converts the MAX_PHYSMEM_BITS macro to 36 if LPAE is
enabled for the ARM architecture.

The conventional section size on EXYNOS is 256M due to sparsemem.
Since EXYNOS5440 has memory in multiples of 1G in 32-bit and 36-bit
range, this has now been modified to 31.

Linus Torvalds 42daabf62b ARM SoC late changes
These are changes that arrived a little late before the merge
 window or that have multiple dependencies on previous branches
 so they did not fit into one of the earlier ones. There
 are 10 branches merged here, a total of 39 non-merge commits.
 Contents are a mixed bag for the above reasons:
 
 * Two new SoC platforms: ST microelectronics stixxxx and
   the TI 'Nspire' graphing calculator. These should have
   been in the 'soc' branch but were a little late
 * Support for the Exynos 5420 variant in mach-exynos,
   which is based on the other exynos branches to avoid
   conflicts.
 * Various small changes for sh-mobile, ux500 and davinci
 * Common clk support for MSM
 
 Conflicts:
 * In Kconfig.debug, various additions trivially conflict,
   the list should be kept in alphabetical order when
   resolving.

Linus Torvalds 3883cbb6c1 ARM SoC specific changes
These changes are all to SoC-specific code, a total of 33 branches on
 17 platforms were pulled into this. Like last time, Renesas sh-mobile
 is now the platform with the most changes, followed by OMAP and EXYNOS.
 
 Two new platforms, TI Keystone and Rockchips RK3xxx are added in
 this branch, both containing almost no platform specific code at all,
 since they are using generic subsystem interfaces for clocks, pinctrl,
 interrupts etc. The device drivers are getting merged through the
 respective subsystem maintainer trees.
 
 One more SoC (u300) is now multiplatform capable and several others
 (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
 towards that goal with this series but need more work.
 
 Also noteworthy is the work on PCI here, which is traditionally part of
 the SoC specific code. With the changes done by Thomas Petazzoni, we can
 now more easily have PCI host controller drivers as loadable modules and
 keep them separate from the platform code in drivers/pci/host. This has
 already led to the discovery that three platforms (exynos, spear and imx)
 are actually using an identical PCIe host controller and will be able
 to share a driver once support for spear and imx is added.
 
 Conflicts:
 * asm/glue-proc.h has one CPU type getting added that conflicts
   with another addition in 3.10-rc7
 * Simple context changes in arch/arm/Makefile and arch/arm/Kconfig

 reason or another the subsystem maintainer preferred to get merged
 through the arm-soc tree. There are both new drivers as well as
 existing drivers that are getting converted from platform-specific
 code into standalone drivers using the appropriate subsystem
 specific interfaces.
 
 In particular, we can now have pinctrl, clk, clksource and irqchip
 drivers in one file per driver, without the need to call into
 platform specific interface, or to get called from platform specific
 code, as long as all information about the hardware is provided
 through a device tree.
 
 Most of the drivers we touch this time are for clocksource. Since
 now most of them are part of drivers/clocksource, I expect that we
 won't have to touch these again from arm-soc and can let the
 clocksource maintainers take care of these in the future.
 
 Another larger part of this series is specific to the exynos platform,
 which is seeing some significant effort in upstreaming and
 modernization of its device drivers this time around, which
 unfortunately is also the cause for the churn and a lot of the
 merge conflicts.
 
 There is one new subsystem that gets merged as part of this series:
 the reset controller interface, which is a very simple interface
 for taking devices on the SoC out of reset or back into reset.
 Patches to use this interface on i.MX follow later in this merge
 window, and we are going to have other platforms (at least tegra
 and sirf) get converted in 3.11. This will let us get rid of
 platform specific callbacks in a number of platform independent
 device drivers.

Linus Torvalds 99c6bcf46d ARM: arm-soc multiplatform updates for 3.10
More multiplatform enablement for ARM platforms. The ones converted in
 this branch are:
 - bcm2835
 - cns3xxx
 - sirf
 - nomadik
 - msx
 - spear
 - tegra
 - ux500
 
 We're getting close to having most of them converted!
 
 One of the larger platforms remaining is Samsung Exynos, and there are
 a bunch of supporting patches in this merge window for it. There was a
 patch in this branch to a early version of multiplatform conversion,
 but it ended up being reverted due to need of more bake time. The
 revert commit is part of the branch since it would have required
 rebasing multiple dependent branches and they were stable by then.

On device tree enabled exynos platforms, retrieve the physical base address
of the chip-id controller from device tree and create a virtual I/O mapping
for the chip-id controller. This helps to remove the chip-id controller entry
from the statically defined I/O mapping tables.

Chanho Park b7bbdbeebd ARM: EXYNOS: Enable PMUs for exynos4
This patch defines irq numbers of ARM performance monitoring unit for exynos4.
Firs of all, we need to fix IRQ_PMU correctly and to split pmu initialization
of exynos from plat-samsung for easily defining it.

The number of CPU cores and PMU irq numbers are vary according to soc types.
So, we need to identify each soc type using soc_is_xxx function and to define
the pmu irqs dynamically. For example, the exynos4412 has 4 cpu cores and pmus.

This patch corrects combined IRQs for exynos4 series platform. The exynos4412
has four extra combined irq group and the exynos4212 has two more combined
irqs
than exynos4210. Each irq is mapped to IRQ_SPI(xx). Unfortunately, extra 4
combined IRQs isn't sequential. So, we need to map the irqs manually.
