Merge tag 'devicetree-for-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring: - Convert /reserved-memory bindings to schemas - Convert a bunch of NFC bindings to schemas - Convert bindings to schema: Xilinx USB, Freescale DDR controller, Arm CCI-400, UBlox Neo-6M, 1-Wire GPIO, MSI controller, ASpeed LPC, OMAP and Inside-Secure HWRNG, register-bit-led, OV5640, Silead GSL1680, Elan ekth3000, Marvell bluetooth, TI wlcore, TI bluetooth, ESP ESP8089, tlm,trusted-foundations, Microchip cap11xx, Ralink SoCs and boards, and TI sysc - New binding schemas for: msi-ranges, Aspeed UART routing controller, palmbus, Xylon LogiCVC display controller, Mediatek's MT7621 SDRAM memory controller, and Apple M1 PCIe host - Run schema checks for %.dtb targets - Improve build time when using DT_SCHEMA_FILES - Improve error message when dtschema is not found - Various doc reference fixes in MAINTAINERS - Convert architectures to common CPU h/w ID parsing function of_get_cpu_hwid(). - Allow for empty NUMA node IDs which may be hotplugged - Cleanup of __fdt_scan_reserved_mem() - Constify device_node parameters - Update dtc to upstream v1.6.1-19-g0a3a9d3449c8. Adds new checks 'node_name_vs_property_name' and 'interrupt_map'. - Enable dtc 'unit_address_format' warning by default - Fix unittest EXPECT text for gpio hog errors * tag 'devicetree-for-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (97 commits) dt-bindings: net: ti,bluetooth: Document default max-speed dt-bindings: pci: rcar-pci-ep: Document r8a7795 dt-bindings: net: qcom,ipa: IPA does support up to two iommus of/fdt: Remove of_scan_flat_dt() usage for __fdt_scan_reserved_mem() of: unittest: document intentional interrupt-map provider build warning of: unittest: fix EXPECT text for gpio hog errors of/unittest: Disable new dtc node_name_vs_property_name and interrupt_map warnings scripts/dtc: Update to upstream version v1.6.1-19-g0a3a9d3449c8 dt-bindings: arm: firmware: tlm,trusted-foundations: Convert txt bindings to yaml dt-bindings: display: tilcd: Fix endpoint addressing in example dt-bindings: input: microchip,cap11xx: Convert txt bindings to yaml dt-bindings: ufs: exynos-ufs: add exynosautov9 compatible dt-bindings: ufs: exynos-ufs: add io-coherency property dt-bindings: mips: convert Ralink SoCs and boards to schema dt-bindings: display: xilinx: Fix example with psgtr dt-bindings: net: nfc: nxp,pn544: Convert txt bindings to yaml dt-bindings: Add a help message when dtschema tools are missing dt-bindings: bus: ti-sysc: Update to use yaml binding dt-bindings: sram: Allow numbers in sram region node name dt-bindings: display: Document the Xylon LogiCVC display controller ...
