Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "This is a slightly larger batch of fixes that we've been sitting on a few -rcs. Most of them are simple oneliners, but there are two sets that are slightly larger and worth pointing out: - A set of patches to OMAP to deal with hwmod for RTC on am33xx (beaglebone SoC, among others). It's the only clock that ever has a valid offset of 0, so a new flag needed introduction once this problem was discovered. - A collection of CCI fixes for performance counters discovered once people started using it on X-Gene CPUs" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (37 commits) arm-cci: pmu: Fix typo in event name Revert "ARM: tegra: fix erroneous address in dts" ARM: dts: imx6qdl: Fix SPDIF regression ARM: imx6: add missing BM_CLPCR_BYPASS_PMIC_READY setting for imx6sx ARM: dts: imx7d-sdb: fix ti,x-plate-ohms property name ARM: dts: kirkwood: Fix PCIe label on OpenRD ARM: kirkwood: ib62x0: fix size of u-boot environment partition bus: arm-ccn: make event groups reliable bus: arm-ccn: fix hrtimer registration bus: arm-ccn: fix PMU interrupt flags ARM: tegra: Correct polarity for Tegra114 PMIC interrupt MAINTAINERS: add tree entry for ARM/UniPhier architecture ARM: sun5i: Fix typo in trip point temperature MAINTAINERS: Switch to kernel.org account for Krzysztof Kozlowski ARM: imx6ul: populates platform device at .init_machine bus: arm-ccn: Add missing event attribute exclusions for host/guest bus: arm-ccn: Correct required arguments for XP PMU events bus: arm-ccn: Fix XP watchpoint settings bitmask bus: arm-ccn: Do not attempt to configure XPs for cycle counter bus: arm-ccn: Fix PMU handling of MN ...
