Pull devicetree updates from Rob Herring:

 - Add Krzysztof Kozlowski as co-maintainer for DT bindings providing
   much needed help.

 - DT schema validation now takes DTB files as input rather than
   intermediate YAML files. This decouples the validation from the
   source level syntax information. There's a bunch of schema fixes as a
   result of switching to DTB based validation which exposed some errors
   and incomplete schemas and examples.

 - Kbuild improvements to explicitly warn users running 'make
   dt_binding_check' on missing yamllint

 - Expand DT_SCHEMA_FILES kbuild variable to take just a partial
   filename or path instead of the full path to 1 file.

 - Convert various bindings to schema format: mscc,vsc7514-switch,
   multiple GNSS bindings, ahci-platform, i2c-at91, multiple UFS
   bindings, cortina,gemini-sata-bridge, cortina,gemini-ethernet, Atmel
   SHA, Atmel TDES, Atmel AES, armv7m-systick, Samsung Exynos display
   subsystem, nuvoton,npcm7xx-timer, samsung,s3c2410-i2c, zynqmp_dma,
   msm/mdp4, rda,8810pl-uart

 - New schemas for u-boot environment variable partition, TI clksel

 - New compatible strings for Renesas RZ/V2L SoC

 - Vendor prefixes for Xen, HPE, deprecated Synopsys, deprecated
   HiSilicon

 - Add/fix schemas for QEMU Arm 'virt' machine

 - Drop unused of_alias_get_alias_list() function

 - Add a script to check DT unittest EXPECT message output. Pass
   messages also now print by default at PR_INFO level to help test
   automation.

-Qualcomm adreno/snapdragon MDP4 display controller
-
-Description:
-
-This is the bindings documentation for the MDP4 display controller found in
-SoCs like MSM8960, APQ8064 and MSM8660.
-
-Required properties:
-- compatible:
-  * "qcom,mdp4" - mdp4
-- reg: Physical base address and length of the controller's registers.
-- interrupts: The interrupt signal from the display controller.
-- clocks: device clocks
-  See ../clocks/clock-bindings.txt for details.
-- clock-names: the following clocks are required.
-  * "core_clk"
-  * "iface_clk"
-  * "bus_clk"
-  * "lut_clk"
-  * "hdmi_clk"
-  * "tv_clk"
-- ports: contains the list of output ports from MDP. These connect to interfaces
-  that are external to the MDP hardware, such as HDMI, DSI, EDP etc (LVDS is a
-  special case since it is a part of the MDP block itself).
-
-  Each output port contains an endpoint that describes how it is connected to an
-  external interface. These are described by the standard properties documented
-  here:
-	Documentation/devicetree/bindings/graph.txt
-	Documentation/devicetree/bindings/media/video-interfaces.txt
-
-  The output port mappings are:
-	Port 0 -> LCDC/LVDS
-	Port 1 -> DSI1 Cmd/Video
-	Port 2 -> DSI2 Cmd/Video
-	Port 3 -> DTV
-
-Optional properties:
-- clock-names: the following clocks are optional:
-  * "lut_clk"
-- qcom,lcdc-align-lsb: Boolean value indicating that LSB alignment should be
-  used for LCDC. This is only valid for 18bpp panels.
-
-Example:
-
-/ {
-	...
-
-	hdmi: hdmi@4a00000 {
-		...
-		ports {
-			...
-			port@0 {
-				reg = <0>;
-				hdmi_in: endpoint {
-					remote-endpoint = <&mdp_dtv_out>;
-				};
-			};
-			...
-		};
-		...
-	};
-

-		interrupts = <GIC_SPI 75 0>;
-		clock-names =
-		    "core_clk",
