Merge tag 'armsoc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "A smallish batch of fixes, a little more than expected this late, but all fixes are contained to their platforms and seem reasonably low risk: - a somewhat large SMP fix for ux500 that still seemed warranted to include here - OMAP DT fixes for pbias regulator specification that broke due to some DT reshuffling - PCIe IRQ routing bugfix for i.MX - networking fixes for keystone - runtime PM for OMAP GPMC - a couple of error path bug fixes for exynos" * tag 'armsoc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: dts: keystone: Fix the mdio bindings by moving it to soc specific file ARM: dts: keystone: fix the clock node for mdio memory: omap-gpmc: Don't try to save uninitialized GPMC context ARM: imx6: correct i.MX6 PCIe interrupt routing ARM: ux500: add an SMP enablement type and move cpu nodes ARM: dts: dra7: Fix broken pbias device creation ARM: dts: OMAP5: Fix broken pbias device creation ARM: dts: OMAP4: Fix broken pbias device creation ARM: dts: omap243x: Fix broken pbias device creation ARM: EXYNOS: fix double of_node_put() on error path ARM: EXYNOS: Fix potentian kfree() of ro memory
