Merge tag 'devicetree-for-6.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
"Bindings:
- Convert Qcom IOMMU, Amlogic timer, Freescale sec-v4.0, Toshiba
TC358764 display bridge, Parade PS8622 display bridge, and Xilinx
FPGA bindings to DT schema format
- Add qdu1000 and sa8775p SoC support to Qcom PDC interrupt
controller
- Add MediaTek MT8365 UART and SYSIRQ bindings
- Add Arm Cortex-A78C and X1C core compatibles
- Add vendor prefix for Novatek
- Remove bindings for stih415, sti416, stid127 platforms
- Drop uneeded quotes in schema files. This is preparation for
yamllint checking quoting for us.
- Add missing (unevaluated|additional)Properties constraints on child
node schemas
- Clean-up schema comments formatting
- Fix I2C and SPI node bus names in schema examples
- Clean-up some display compatibles schema syntax
- Fix incorrect references to lvds.yaml
- Gather all cache controller bindings in a common directory
DT core:
- Convert unittest to new void .remove platform device hook
- kerneldoc fixes for DT address of_pci_range_to_resource/
of_address_to_resource functions"
