Merge tag 'devicetree-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
"DT Bindings:
- Various LED binding conversions and clean-ups. Convert the
ir-spi-led, pwm-ir-tx, and gpio-ir-tx LED bindings to schemas.
Consistently reference LED common.yaml or multi-led schemas and
disallow undefined properties.
- Convert IDT 89HPESx, pwm-clock, st,stmipid02, Xilinx PCIe hosts,
and fsl,imx-fb bindings to schema
- Add ata-generic, Broadcom u-boot environment, and dynamic MTD
sub-partitions bindings.
- Make all SPI based displays reference spi-peripheral-props.yaml
- Fix some schema property regex's which should be fixed strings or
were missing start/end anchors
- Remove 'status' in examples, again...
DT Core:
- Fix a possible NULL dereference in overlay functions
- Fix kexec reading 32-bit "linux,initrd-{start,end}" values (which
never worked)
- Add of_address_count() helper to count number of 'reg' entries
- Support .dtso extension for DT overlay source files. Rename staging
and unittest overlay files.
- Update dtc to upstream v1.6.1-63-g55778a03df61"
