Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "Our first real batch of fixes this release cycle. Nothing really concerning, and diffstat is a bit inflated due to some DT contents moving around on STi platforms. There's a collection of them here: - A fixup for a build breakage that hits on arm64 allmodconfig in QCOM SCM firmware drivers - MMC fixes for OMAP that had quite a bit of breakage this merge window. - Misc build/warning fixes on PXA and OMAP - A couple of minor fixes for Beagleboard X15 which is now starting to see a few more users in the wild" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (31 commits) ARM: sti: dt: adapt DT to fix probe/bind issues in DRM driver ARM: dts: fix omap2+ address translation for pbias firmware: qcom: scm: Add function stubs for ARM64 ARM: dts: am57xx-beagle-x15: use palmas-usb for USB2 ARM: omap2plus_defconfig: enable GPIO_PCA953X ARM: dts: omap5-uevm.dts: fix i2c5 pinctrl offsets ARM: OMAP2+: AM43XX: Enable autoidle for clks in am43xx_init_late ARM: dts: am57xx-beagle-x15: Update Phy supplies ARM: pxa: balloon3: Fix build error ARM: dts: Fixup model name for HP t410 dts ARM: dts: DRA7: fix a typo in ethernet ARM: omap2plus_defconfig: make PCF857x built-in ARM: dts: Use ti,pbias compatible string for pbias ARM: OMAP5: Cleanup options for SoC only build ARM: DRA7: Select missing options for SoC only build ARM: OMAP2+: board-generic: Remove stale of_irq macros ARM: OMAP4+: PM: erratum is used by OMAP5 and DRA7 as well ARM: dts: omap3-igep: Move eth IRQ pinmux to IGEPv2 common dtsi ARM: dts: am57xx-beagle-x15: Add wakeup irq for mcp79410 ARM: dts: am335x-phycore-som: Fix mpu voltage ...
