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 ...
