Merge tag 'devicetree-for-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
- Refine reserved memory nomap handling
- Merge some PCI and non-PCI address handling implementations
- Simplify of_address.h header ifdefs
- Improve printk handling of some 64-bit types
- Convert adi,adv7511, Arm ccree, Arm SCMI, Arm SCU, Arm TWD timer, Arm
VIC, arm,sbsa-gwdt, Arm/Amlogic SCPI, Aspeed I2C, Broadcom iProc PWM,
linaro,optee-tz, MDIO GPIO, Mediatek RNG, MTD physmap, NXP
pcf8563/pcf85263/pcf85363, Renesas TPU, renesas,emev2-smu,
renesas,r9a06g032-sysctrl, sysc-rmobile, Tegra20 EMC, TI AM56 PCI, TI
OMAP mailbox, TI SCI bindings, virtio-mmio, Zynq FPGA, and ZynqMP RTC
to DT schema
- Convert mux and mux controller bindings to schema. This includes MDIO
IIO, and I2C muxes.
- Add Arm PL031 RTC binding schema
- Add vendor prefixes for StarFive Technology Co. Ltd. and Insignal Ltd
- Fix some stale doc references
- Remove stale property-units.txt. Superseded by schema in dt-schema
repo.
- Fixes for 'unevaluatedProperties' handling (enabled with experimental
json-schema support)
- Drop redundant usage of minItems and maxItems across the tree
- Update some examples to use bindings with a schema
