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
