Merge tag 'devicetree-for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree updates from Rob Herring:

 - Unit test for overlays with GPIO hogs

 - Improve dma-ranges parsing to handle dma-ranges with multiple entries

 - Update dtc to upstream version v1.6.0-2-g87a656ae5ff9

 - Improve overlay error reporting

 - Device link support for power-domains and hwlocks bindings

 - Add vendor prefixes for Beacon, Topwise, ENE, Dell, SG Micro, Elida,
   PocketBook, Xiaomi, Linutronix, OzzMaker, Waveshare Electronics, and
   ITE Tech

 - Add deprecated Marvell vendor prefix 'mrvl'

 - A bunch of binding conversions to DT schema continues. Of note, the
   common serial and USB connector bindings are converted.

 - Add more Arm CPU compatibles

 - Drop Mark Rutland as DT maintainer :(

-UniPhier Media IO DMA controller
-
-This works as an external DMA engine for SD/eMMC controllers etc.
-found in UniPhier LD4, Pro4, sLD8 SoCs.
-
-Required properties:
-- compatible: should be "socionext,uniphier-mio-dmac".
-- reg: offset and length of the register set for the device.
-- interrupts: a list of interrupt specifiers associated with the DMA channels.
-- clocks: a single clock specifier.
-- #dma-cells: should be <1>. The single cell represents the channel index.
-
-Example:
-	dmac: dma-controller@5a000000 {
-		compatible = "socionext,uniphier-mio-dmac";
-		reg = <0x5a000000 0x1000>;
-		interrupts = <0 68 4>, <0 68 4>, <0 69 4>, <0 70 4>,
-			     <0 71 4>, <0 72 4>, <0 73 4>, <0 74 4>;
-		clocks = <&mio_clk 7>;
-		#dma-cells = <1>;
-	};
-
-Note:
-In the example above, "interrupts = <0 68 4>, <0 68 4>, ..." is not a typo.
-The first two channels share a single interrupt line.
