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

-Required properties:
-- compatible: Must be "marvell,mmp2-ssp".
-- reg: Offset and length of the device's register set.
-- interrupts: Should be the interrupt number.
-- clocks: Should contain a single entry describing the clock input.
-- #address-cells:  Number of cells required to define a chip select address.
-- #size-cells: Should be zero.
-
-Optional properties:
-- cs-gpios: list of GPIO chip selects. See the SPI bus bindings,
-  Documentation/devicetree/bindings/spi/spi-bus.txt
-- spi-slave: Empty property indicating the SPI controller is used in slave mode.
-- ready-gpios: GPIO used to signal a SPI master that the FIFO is filled
-  and we're ready to service a transfer. Only useful in slave mode.
-
-Child nodes represent devices on the SPI bus
-  See ../spi/spi-bus.txt
