Merge tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC late updates from Olof Johansson: "A couple of late-merged changes that would be useful to get in this merge window: - Driver support for reset of audio complex on Meson platforms. The audio driver went in this merge window, and these changes have been in -next for a while (just not in our tree). - Power management fixes for IOMMU on Rockchip platforms, getting closer to kexec working on them, including Chromebooks. - Another pass updating "arm,psci" -> "psci" for some properties that have snuck in since last time it was done" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: iommu/rockchip: Move irq request past pm_runtime_enable iommu/rockchip: Handle errors returned from PM framework arm64: rockchip: Force CONFIG_PM on Rockchip systems ARM: rockchip: Force CONFIG_PM on Rockchip systems arm64: dts: Fix various entry-method properties to reflect documentation reset: imx7: Fix always writing bits as 0 reset: meson: add meson audio arb driver reset: meson: add dt-bindings for meson-axg audio arb

+* Amlogic audio memory arbiter controller
+
+The Amlogic Audio ARB is a simple device which enables or
+disables the access of Audio FIFOs to DDR on AXG based SoC.
+
+Required properties:
+- compatible: 'amlogic,meson-axg-audio-arb'
+- reg: physical base address of the controller and length of memory
+ mapped region.
+- clocks: phandle to the fifo peripheral clock provided by the audio
+ clock controller.
+- #reset-cells: must be 1.
+
+Example on the A113 SoC:
+
+arb: reset-controller@280 {
+ compatible = "amlogic,meson-axg-audio-arb";
+ reg = <0x0 0x280 0x0 0x4>;
+ #reset-cells = <1>;
+ clocks = <&clkc_audio AUD_CLKID_DDR_ARB>;
+};
