Merge tag 'devicetree-for-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull Devicetree updates from Rob Herring:

 - DT schemas for PWM, syscon, power domains, SRAM, syscon-reboot,
   syscon-poweroff, renesas-irqc, simple-pm-bus, renesas-bsc, pwm-rcar,
   Renesas tpu, at24 eeprom, rtc-sh, Allwinner PS/2, sharp,ld-d5116z01b
   panel, Arm SMMU, max77650, Meson CEC, Amlogic canvas and DWC3 glue,
   Allwinner A10 mUSB and CAN, TI Davinci MDIO, QCom QCS404
   interconnect, Unisoc/Spreadtrum SoCs and UART

 - Convert a bunch of Samsung bindings to DT schema

 - Convert a bunch of ST stm32 bindings to DT schema

 - Realtek and Exynos additions to Arm Mali bindings

 - Fix schema errors in RiscV CPU schema

 - Various schema fixes from improved meta-schema checks

 - Improve the handling of 'dma-ranges' and in particular fix DMA mask
   setup on PCI bridges

 - Fix a memory leak in add_changeset_property() and DT unit tests.

 - Several documentation improvements for schema validation

 - Rework build rules to improve schema validation errors

 - Color output for dtx_diff

-Qualcomm QCS404 Network-On-Chip interconnect driver binding
------------------------------------------------------------
-
-Required properties :
-- compatible : shall contain only one of the following:
-			"qcom,qcs404-bimc"
-			"qcom,qcs404-pcnoc"
-			"qcom,qcs404-snoc"
-- #interconnect-cells : should contain 1
-
-reg : specifies the physical base address and size of registers
-clocks : list of phandles and specifiers to all interconnect bus clocks
-clock-names : clock names should include both "bus" and "bus_a"
-
-Example:
-
-soc {
-	...
-	bimc: interconnect@400000 {
-		reg = <0x00400000 0x80000>;
-		compatible = "qcom,qcs404-bimc";
