Merge tag 'devicetree-for-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull Devicetree updates from Rob Herring:
- DT schemas for PWM, syscon, power domains, SRAM, syscon-reboot,
syscon-poweroff, renesas-irqc, simple-pm-bus, renesas-bsc, pwm-rcar,
Renesas tpu, at24 eeprom, rtc-sh, Allwinner PS/2, sharp,ld-d5116z01b
panel, Arm SMMU, max77650, Meson CEC, Amlogic canvas and DWC3 glue,
Allwinner A10 mUSB and CAN, TI Davinci MDIO, QCom QCS404
interconnect, Unisoc/Spreadtrum SoCs and UART
- Convert a bunch of Samsung bindings to DT schema
- Convert a bunch of ST stm32 bindings to DT schema
- Realtek and Exynos additions to Arm Mali bindings
- Fix schema errors in RiscV CPU schema
- Various schema fixes from improved meta-schema checks
- Improve the handling of 'dma-ranges' and in particular fix DMA mask
setup on PCI bridges
- Fix a memory leak in add_changeset_property() and DT unit tests.
- Several documentation improvements for schema validation
- Rework build rules to improve schema validation errors
- Color output for dtx_diff
