Linus Torvalds 44598f98b9 ARM: SoC board updates for 3.12
Board updates for 3.12. Again, a bit of domain overlap with SoC and DT branches,
 but most of this is around legacy code and board support. We've found that
 platform maintainers have a hard time separating all of these out and might
 move towards fewer branches for next release.
 
 - Removal of a number of Marvell Kirkwood board files, since contents
   is now common and mostly configured via DT.
 - Device-tree updates for Marvell Dove, including irqchip and clocksource
   setup.
 - Defconfig updates. Gotta go somewhere. One new one for Renesas Lager.
 - New backlight drivers for backlights used on Renesas shmobile platforms.
 - Removal of Renesas leds driver.
 - Shuffling of some of the new Broadcom platforms to give room for others in
   the same mach directory. More in 2.13.

Linus Torvalds b4b50fd78b ARM: SoC platform changes for 3.12
This branch contains mostly additions and changes to platform enablement
 and SoC-level drivers. Since there's sometimes a dependency on device-tree
 changes, there's also a fair amount of those in this branch.
 
 Pieces worth mentioning are:
 
 - Mbus driver for Marvell platforms, allowing kernel configuration
   and resource allocation of on-chip peripherals.
 - Enablement of the mbus infrastructure from Marvell PCI-e drivers.
 - Preparation of MSI support for Marvell platforms.
 - Addition of new PCI-e host controller driver for Tegra platforms
 - Some churn caused by sharing of macro names between i.MX 6Q and 6DL
   platforms in the device tree sources and header files.
 - Various suspend/PM updates for Tegra, including LP1 support.
 - Versatile Express support for MCPM, part of big little support.
 - Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7)
 - OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
 
 The code that touches other architectures are patches moving
 MSI arch-specific functions over to weak symbols and removal of
 ARCH_SUPPORTS_MSI, acked by PCI maintainers.

Thomas Petazzoni 7d55490277 arm: mach-dove: convert to use mvebu-mbus driver
This commit migrates the mach-dove platforms to use the mvebu-mbus
driver and therefore removes the Dove-specific addr-map code.

The dove_init_early() function now initializes the mvebu-mbus driver
by calling mvebu_mbus_init().

The address decoding windows are now registered in the
dove_setup_cpu_wins() function. It is worth noting that the four PCIe
address decoding windows will ultimately no longer have to be
registered here: it will be done automatically by the PCIe driver once
Dove has been migrated to use the upcoming mvebu PCIe driver.

Linus Torvalds 1a32c58bb9 arm-soc: mvebu platform changes
This series contains changes for the Marvell EBU platforms (mvebu,
 orion, kirkwood, dove) that were not part of the first set of pull
 requests because of dependencies on the MMC tree, and being submitted
 a little late.
 
 Notable changes are:
 
 * More devices get moved out of board files into device tree
   descriptions. The remaining devices listed in there have patches
   that will get sent for 3.10, after which we can remove a lot of the
   board files entirely. We are doing the pinctrl and mmc drivers here,
   ethernet and PCI still remain.
 
 * SMP support for mvebu is improved with support for the
   local interrupt controller.
 
 * The Guruplug board file gets replaced with a DT description.
 
 Unfortunately, the dependency on the MMC tree turned out to be a much
 larger problem than expected, when the MMC maintainer rebased the patches
 in his tree that all of the patches in this branch are based on, which
 caused merge conflicts between the new and old versions of those patches.
 
 To work around the merge conflicts, this branch rebases all patches
 on top of the respective MMC patches that did get merged into 3.9.
 The patches are all identical to the versions that were part of
 linux-next, but have a new commit date.
 
 Merge conflicts:
 
 * in board-nsa310.c, the gpio.h inclusion was removed prematurely and
   put back as a bug fix earlier. With this series it is really not needed
   any more.
 
 * The patch to add rtc support was already applied by Andrew Morton,
   and conflicts with a second copy that was in this series, which adds
   a lot of other devices to arch/arm/boot/dts/armada-370-xp.dtsi.

Merge tag 'late-mvebu-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC mvebu platform changes from Olof Johansson:
 "This series contains changes for the Marvell EBU platforms (mvebu,
  orion, kirkwood, dove) that were not part of the first set of pull
  requests because of dependencies on the MMC tree, and being submitted
  a little late.

  Notable changes are:

   - More devices get moved out of board files into device tree
     descriptions.  The remaining devices listed in there have patches
     that will get sent for 3.10, after which we can remove a lot of the
     board files entirely.  We are doing the pinctrl and mmc drivers
     here, ethernet and PCI still remain.

   - SMP support for mvebu is improved with support for the local
     interrupt controller.

   - The Guruplug board file gets replaced with a DT description.

  Unfortunately, the dependency on the MMC tree turned out to be a much
  larger problem than expected, when the MMC maintainer rebased the
  patches in his tree that all of the patches in this branch are based
  on, which caused merge conflicts between the new and old versions of
  those patches.

  To work around the merge conflicts, this branch rebases all patches on
  top of the respective MMC patches that did get merged into 3.9.  The
  patches are all identical to the versions that were part of
  linux-next, but have a new commit date."

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

Russell King - ARM Linux 5d3df93542 Dove: Attempt to fix PMU/RTC interrupts
Fix the acknowledgement of PMU interrupts on Dove: some Dove hardware
has not been sensibly designed so that interrupts can be handled in a
race free manner.  The PMU is one such instance.

The pending (aka 'cause') register is a bunch of RW bits, meaning that
these bits can be both cleared and set by software (confirmed on the
Armada-510 on the cubox.)

Hardware sets the appropriate bit when an interrupt is asserted, and
software is required to clear the bits which are to be processed.  If
we write ~(1 << bit), then we end up asserting every other interrupt
except the one we're processing.  So, we need to do a read-modify-write
cycle to clear the asserted bit.

However, any interrupts which occur in the middle of this cycle will
also be written back as zero, which will also clear the new interrupts.

The upshot of this is: there is _no_ way to safely clear down interrupts
in this register (and other similarly behaving interrupt pending
registers on this device.)  The patch below at least stops us creating
new interrupts.

Context conflicts in arch/arm/Kconfig and arch/arm/mach-dove/common.c.

The new device trees added to arch/arm/mach-kirkwood/Makefile.boot are
kept and dealt with in a separate changeset, since moving them out to
the new Makefile in this merge commit doesn't work well.

Thomas Petazzoni 9b7b7d8b02 arm: plat-orion: use void __iomem pointers for addr-map functions
The functions for address mapping management now take void __iomem
pointers, so we remove the temporary "unsigned long" casts from the
mach-*/common.c files.

Thomas Petazzoni c3c5a2815d arm: mach-dove: use IOMEM() for base address definitions
We now define all virtual base address constants using IOMEM() so that
those are naturally typed as void __iomem pointers, and we do the
necessary adjustements in the mach-dove code.

Note that we introduce a few temporary additional "unsigned long"
casts when calling into plat-orion functions. Those are removed by
followup patches converting plat-orion functions to void __iomem
pointers as well.

Thomas Petazzoni 73b39d4b44 arm: mach-dove: use plus instead of or for address definitions
Since we are going to use IOMEM() to define many base virtual
addresses, we can no longer use binary or to define the individual
register addresses ("binary or" arithmetic on pointers is not
allowed). Instead, use the more conventional plus operator to do so.

The binary or operators were actually not useful because the low-order
bits of the base address were always zero, so the usage of the binary
or operators was effectively identical to a plus operator.
