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 ...

-* Renesas Multi-Function Timer Pulse Unit 2 (MTU2)
-
-The MTU2 is a multi-purpose, multi-channel timer/counter with configurable
-clock inputs and programmable compare match.
-
-Channels share hardware resources but their counter and compare match value
-are independent. The MTU2 hardware supports five channels indexed from 0 to 4.
-
-Required Properties:
-
- - compatible: must be one or more of the following:
- - "renesas,mtu2-r7s72100" for the r7s72100 MTU2
- - "renesas,mtu2" for any MTU2
- This is a fallback for the above renesas,mtu2-* entries
-
- - reg: base address and length of the registers block for the timer module.
-
- - interrupts: interrupt specifiers for the timer, one for each entry in
- interrupt-names.
- - interrupt-names: must contain one entry named "tgi?a" for each enabled
- channel, where "?" is the channel index expressed as one digit from "0" to
- "4".
-
- - clocks: a list of phandle + clock-specifier pairs, one for each entry
- in clock-names.
- - clock-names: must contain "fck" for the functional clock.
-
-
-Example: R7S72100 (RZ/A1H) MTU2 node
-
- mtu2: timer@fcff0000 {
- compatible = "renesas,mtu2-r7s72100", "renesas,mtu2";
- reg = <0xfcff0000 0x400>;
- interrupts = <0 139 IRQ_TYPE_LEVEL_HIGH>,
- <0 146 IRQ_TYPE_LEVEL_HIGH>,
- <0 150 IRQ_TYPE_LEVEL_HIGH>,
- <0 154 IRQ_TYPE_LEVEL_HIGH>,
- <0 159 IRQ_TYPE_LEVEL_HIGH>;
- interrupt-names = "tgi0a", "tgi1a", "tgi2a", "tgi3a", "tgi4a";
- clocks = <&mstp3_clks R7S72100_CLK_MTU2>;
- clock-names = "fck";
- };
