Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM DT updates from Olof Johansson: "As usual, the bulk of this release is again DT file contents. There's a huge number of changes here, and it's challenging to give a crisp overview of just what is in here. To start with: New boards: - TI-based DM3730 from LogicPD (Torpedo) - Cosmic+ M4 (nommu) initial support (Freescale Vybrid) - Raspberry Pi 2 DT files - Watchdog on Meson8b - Veyron-mickey (ASUS Chromebit) DTS - Rockchip rk3228 SoC and eval board - Sigma Designs Tango4 Improvements: - Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files - Misc new devices for Rockchip rk3036 and rk3288 - Allwinner updates for misc SoCs and systems ... and a _large_ number of other changes across the field. Devices added to SoC DTSI and board DTS files for a number of SoC vendors, new product boards on already-supported SoCs, cleanups and refactorings of existing DTS/DTSI files and a bunch of other changes" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (469 commits) ARM: dts: compulab: add new board description ARM: versatile: add the syscon LEDs to the DT dts: vt8500: Fix errors in SDHC node for WM8505 ARM: dts: imx6q: clean up unused ipu2grp ARM: dts: silk: Add compatible property to "partitions" node ARM: dts: gose: Add compatible property to "partitions" node ARM: dts: porter: Add compatible property to "partitions" node ARM: dts: koelsch: Add compatible property to "partitions" node ARM: dts: lager: Add compatible property to "partitions" node ARM: dts: bockw: Add compatible property to "partitions" node ARM: dts: meson8b: Add watchdog node Documentation: watchdog: Add new bindings for meson8b ARM: meson: Add status LED for Odroid-C1 ARM: dts: uniphier: fix a typo in comment block ARM: bcm2835: Add the auxiliary clocks to the device tree.

+Device Tree bindings for Marvell PMU
+
+Required properties:
+ - compatible: value should be "marvell,dove-pmu".
+ May also include "simple-bus" if there are child devices, in which
+ case the ranges node is required.
+ - reg: two base addresses and sizes of the PM controller and PMU.
+ - interrupts: single interrupt number for the PMU interrupt
+ - interrupt-controller: must be specified as the PMU itself is an
+ interrupt controller.
+ - #interrupt-cells: must be 1.
+ - #reset-cells: must be 1.
+ - domains: sub-node containing domain descriptions
+
+Optional properties:
+ - ranges: defines the address mapping for child devices, as per the
+ standard property of this name. Required when compatible includes
+ "simple-bus".
+
+Power domain descriptions are listed as child nodes of the "domains"
+sub-node. Each domain has the following properties:
+
+Required properties:
+ - #power-domain-cells: must be 0.
+
+Optional properties:
+ - marvell,pmu_pwr_mask: specifies the mask value for PMU power register
+ - marvell,pmu_iso_mask: specifies the mask value for PMU isolation register
+ - resets: points to the reset manager (PMU node) and reset index.
+
+Example:
+
+ pmu: power-management@d0000 {
+ compatible = "marvell,dove-pmu";
+ reg = <0xd0000 0x8000>, <0xd8000 0x8000>;
+ interrupts = <33>;
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ #reset-cells = <1>;
+
+ domains {
+ vpu_domain: vpu-domain {
+ #power-domain-cells = <0>;
+ marvell,pmu_pwr_mask = <0x00000008>;
+ marvell,pmu_iso_mask = <0x00000001>;
+ resets = <&pmu 16>;
+ };
+
+ gpu_domain: gpu-domain {
+ #power-domain-cells = <0>;
+ marvell,pmu_pwr_mask = <0x00000004>;
+ marvell,pmu_iso_mask = <0x00000002>;
+ resets = <&pmu 18>;
+ };
+ };
+ };
