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

- - reg : the I2C address or SPI chip select number of the sensor
- - spi-max-frequency : set maximum clock frequency (only for SPI)
-
-Optional properties:
