Pull ARM SoC platform updates (part 3) from Arnd Bergmann:
"This is the third and smallest of the SoC specific updates. Changes
include:
- SMP support for the Xilinx zynq platform
- Smaller imx changes
- LPAE support for mvebu
- Moving the orion5x, kirkwood, dove and mvebu platforms to a common
"mbus" driver for their internal devices.
It would be good to get feedback on the location of the "mbus" driver.
Since this is used on multiple platforms may potentially get shared
with other architectures (powerpc and arm64), it was moved to
drivers/bus/. We expect other similar drivers to get moved to the
same place in order to avoid creating more top-level directories under
drivers/ or cluttering up the messy drivers/misc/ even more."

Pull ARM SoC board specific changes (part 1) from Olof Johansson: "These changes are all for board specific files. These used to make up a large portion of the ARM changes in the past, but as we are generalizing the support and moving to device tree probing, this has gotten significantly smaller. The only platform actually adding new code here at the moment is Renesas shmobile, as they are still busy converting their code to device tree and have not come far enough to not need it." * tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (43 commits) ARM: msm: USB_MSM_OTG needs USB_PHY ARM: davinci: da850 evm: fix const qualifier placement ARM: davinci: da850 board: add remoteproc support ARM: pxa: move debug uart code ARM: pxa: select PXA935 on saar & tavorevb ARM: mmp: add more compatible names in gpio driver ARM: pxa: move PXA_GPIO_TO_IRQ macro ARM: pxa: remove cpu_is_xxx in gpio driver ARM: Kirkwood: update Network Space Mini v2 description ARM: Kirkwood: DT board setup for CloudBox ARM: Kirkwood: sort board entries by ASCII-code order ARM: OMAP: board-4430sdp: Provide regulator to pwm-backlight ARM: OMAP: zoom: Use pwm stack for lcd and keyboard backlight ARM: OMAP2+: omap2plus_defconfig: Add support for BMP085 pressure sensor omap2+: Remove useless Makefile line omap2+: Remove useless Makefile line ARM: OMAP: RX-51: add missing regulator supply definitions for lis3lv02d ARM: OMAP1: fix omap_udc registration ARM: davinci: use is IS_ENABLED macro ARM: kirkwood: add MACH_GURUPLUG_DT to defconfig ...
Pull ARM updates from Russell King:
"The major items included in here are:
- MCPM, multi-cluster power management, part of the infrastructure
required for ARMs big.LITTLE support.
- A rework of the ARM KVM code to allow re-use by ARM64.
- Error handling cleanups of the IS_ERR_OR_NULL() madness and fixes
of that stuff for arch/arm
- Preparatory patches for Cortex-M3 support from Uwe Kleine-König.
There is also a set of three patches in here from Hugh/Catalin to
address freeing of inappropriate page tables on LPAE. You already
have these from akpm, but they were already part of my tree at the
time he sent them, so unfortunately they'll end up with duplicate
commits"

These patches get us closer to adding multiplatform support on the Exynos platform, they are part of a longer series of patches. This would get all the simple stuff out of the way, and I don't think there is a big risk of introducing regressions with these. A lot of the other patches have already been merged into subsystem trees. After this series in in arm-soc, what is left comes down to * The ASoC conversion to dmaengine won't make it unless someone who knows that code better steps up to do it right away. This means that we won't have audio in a 3.10 multiplatform kernel on Exynos, but it will still work for users that don't enable multiplatform. * The irqchip (combiner), clk and clksource patches are all based on top of other changesets we pulled in from your trees, so I would not make them part of the next/multiplatform branch. We can apply them on top of the next/drivers branch once they are tested successfully. * A trivial patch is needed in the end to actually make CONFIG_ARCH_EXYNOS visible in multiplatform configurations. We will do that as a separate patch once everything else is there. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
The move is necessary to support early debug output on exynos with multiplatform configurations. This implies also moving the plat/debug-macro.S file, but we are leaving the remaining users of that file in place, to avoid adding large numbers of extra configuration options to Kconfig.debug Signed-off-by: Arnd Bergmann <arnd@arndb.de>
