Merge tag 'devicetree-for-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull Devicetree updates from Rob Herring: - a bunch of DT binding conversions to DT schema format - clean-ups of the Arm idle-states binding - support a default number of cells in of_for_each_phandle() when the cells name is missing - expose dtbs_check and dt_binding_check in the make help - convert writting-schema.md to ReST - HiSilicon reset controller binding updates - add documentation for MT8516 RNG * tag 'devicetree-for-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (46 commits) of: restore old handling of cells_name=NULL in of_*_phandle_with_args() bus: qcom: fix spelling mistake "ambigous" -> "ambiguous" of: Let of_for_each_phandle fallback to non-negative cell_count iommu: pass cell_count = -1 to of_for_each_phandle with cells_name dt-bindings: arm: Convert Realtek board/soc bindings to json-schema dt-bindings: arm: Convert Actions Semi bindings to jsonschema dt-bindings: Correct spelling in example schema dt-bindings: cpu: Add a support cpu type for cortex-a55 dt-bindings: gpu: mali-midgard: Add samsung exynos5250 compatible dt-bindings: arm: idle-states: Move exit-latency-us explanation dt-bindings: arm: idle-states: Add punctuation to improve readability dt-bindings: arm: idle-states: Correct "constraint guarantees" dt-bindings: arm: idle-states: Correct references to wake-up delay dt-bindings: arm: idle-states: Use "e.g." and "i.e." consistently pinctrl-mcp23s08: Fix property-name in dt-example dt-bindings: Clarify interrupts-extended usage dt-bindings: Convert Arm Mali Utgard GPU to DT schema dt-bindings: Convert Arm Mali Bifrost GPU to DT schema dt-bindings: Convert Arm Mali Midgard GPU to DT schema dt-bindings: irq: Convert Allwinner NMI Controller to a schema ...
