Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC fixes from Arnd Bergmann: "This week is a much smaller update, containing fixes only for TI OMAP, NXP i.MX and Rockchips platforms: omap: - omap4 had problems with lost timer interrupts - another IRQ handling issue with OMAP5 - A workaround for a regression in the pwm-omap-dmtimer driver NXP i.MX: - eMMC was broken on the new imx8mq-evk board Rockchip: - a fix for new dtc graph warnings and a regulator fix for rock64 - USB support broke on rk3328-rock64" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: ARM: OMAP2+: fix lack of timer interrupts on CPU1 after hotplug arm64: dts: imx8mq: Fix boot from eMMC ARM: OMAP2+: Variable "reg" in function omap4_dsi_mux_pads() could be uninitialized ARM: dts: Configure clock parent for pwm vibra bus: ti-sysc: Fix timer handling with drop pm_runtime_irq_safe() arm64: dts: rockchip: enable usb-host regulators at boot on rk3328-rock64 arm64: dts: rockchip: fix graph_port warning on rk3399 bob kevin and excavator ARM: OMAP5+: Fix inverted nirq pin interrupts with irq_set_type clocksource: timer-ti-dm: Fix pwm dmtimer usage of fck reparenting ARM: dts: rockchip: remove qos_cif1 from rk3188 power-domain
