Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "Again, a batch that's been sitting a couple of weeks, mostly because I anticipated a bit more material but it didn't show up -- which is good. These are all your garden variety fixes for ARM platforms. The most visible issue fixed here is probably the SMP reset issue on OMAP, the rest are minor stuff" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: arm64: allwinner: a64: add pmu0 regs for USB PHY ARM: OMAP2+: omap_device: Sync omap_device and pm_runtime after probe defer reset: add exported __reset_control_get, return NULL if optional ARM: orion5x: only call into phylib when available ARM: omap2+: Revert omap-smp.c changes resetting CPU1 during boot ARM: dts: am335x-evmsk: adjust mmc2 param to allow suspend ARM: dts: ti: fix PCI bus dtc warnings ARM: dts: am335x-baltos: disable EEE for Atheros 8035 PHY ARM: dts: OMAP3: Fix MFG ID EEPROM ARM: sun8i: a33: add operating-points-v2 property to all nodes ARM: sun8i: a33: remove highest OPP to fix CPU crashes
