Merge tag 'devicetree-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull Devicetree updates from Rob Herring:

 - DT binding schema examples are now validated against the schemas.
   Various examples are fixed due to that.

 - Sync dtc with upstream version v1.5.0-30-g702c1b6c0e73

 - Initial schemas for networking bindings. This includes ethernet, phy
   and mdio common bindings with several Allwinner and stmmac converted
   to the schema.

 - Conversion of more Arm top-level SoC/board bindings to DT schema

 - Conversion of PSCI binding to DT schema

 - Rework Arm CPU schema to coexist with other CPU schemas

 - Add a bunch of missing vendor prefixes and new ones for SoChip,
   Sipeed, Kontron, B&R Industrial Automation GmbH, and Espressif

 - Add Mediatek UART RX wakeup support to binding

 - Add reset to ST UART binding

 - Remove some Linuxisms from the endianness common-properties.txt
   binding

 - Make the flattened DT read-only after init

 - Ignore disabled reserved memory nodes

 - Clean-up some dead code in FDT functions
