Merge tag 'devicetree-for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring: - Convert various DT (non-binding) doc files to ReST - Various improvements to device link code - Fix __of_attach_node_sysfs refcounting bug - Add support for 'memory-region-names' with reserved-memory binding - Vendor prefixes for Protonic Holland, BeagleBoard.org, Alps, Check Point, Würth Elektronik, U-Boot, Vaisala, Baikal Electronics, Shanghai Awinic Technology Co., MikroTik, Silex Insight - A bunch more binding conversions to DT schema. Only 3K to go. - Add a minimum version check for schema tools - Treewide dropping of 'allOf' usage with schema references. Not needed in new json-schema spec. - Some formatting clean-ups of schemas * tag 'devicetree-for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (194 commits) dt-bindings: clock: Add documentation for X1830 bindings. dt-bindings: mailbox: Convert imx mu to json-schema dt-bindings: power: Convert imx gpcv2 to json-schema dt-bindings: power: Convert imx gpc to json-schema dt-bindings: Merge gpio-usb-b-connector with usb-connector dt-bindings: timer: renesas: cmt: Convert to json-schema dt-bindings: clock: Convert i.MX8QXP LPCG to json-schema dt-bindings: timer: Convert i.MX GPT to json-schema dt-bindings: thermal: rcar-thermal: Add device tree support for r8a7742 dt-bindings: serial: Add binding for UART pin swap dt-bindings: geni-se: Add interconnect binding for GENI QUP dt-bindings: geni-se: Convert QUP geni-se bindings to YAML dt-bindings: vendor-prefixes: Add Silex Insight vendor prefix dt-bindings: input: touchscreen: edt-ft5x06: change reg property dt-bindings: usb: qcom,dwc3: Introduce interconnect properties for Qualcomm DWC3 driver dt-bindings: timer: renesas: mtu2: Convert to json-schema of/fdt: Remove redundant kbasename function call dt-bindings: clock: Convert i.MX1 clock to json-schema dt-bindings: clock: Convert i.MX21 clock to json-schema dt-bindings: clock: Convert i.MX25 clock to json-schema ...

-* NXP i.MX8QXP LPCG (Low-Power Clock Gating) Clock bindings
-
-The Low-Power Clock Gate (LPCG) modules contain a local programming
-model to control the clock gates for the peripherals. An LPCG module
-is used to locally gate the clocks for the associated peripheral.
-
-Note:
-This level of clock gating is provided after the clocks are generated
-by the SCU resources and clock controls. Thus even if the clock is
-enabled by these control bits, it might still not be running based
-on the base resource.
-
-Required properties:
-- compatible: Should be one of:
- "fsl,imx8qxp-lpcg-adma",
- "fsl,imx8qxp-lpcg-conn",
- "fsl,imx8qxp-lpcg-dc",
- "fsl,imx8qxp-lpcg-dsp",
- "fsl,imx8qxp-lpcg-gpu",
- "fsl,imx8qxp-lpcg-hsio",
- "fsl,imx8qxp-lpcg-img",
- "fsl,imx8qxp-lpcg-lsio",
- "fsl,imx8qxp-lpcg-vpu"
-- reg: Address and length of the register set
-- #clock-cells: Should be <1>
-
-The clock consumer should specify the desired clock by having the clock
-ID in its "clocks" phandle cell.
-See the full list of clock IDs from:
-include/dt-bindings/clock/imx8qxp-clock.h
-
-Examples:
-
-#include <dt-bindings/clock/imx8qxp-clock.h>
