Merge tag 'devicetree-for-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring: "DT core: - Fix node refcounting in of_find_last_cache_level() - Constify device_node in of_device_compatible_match() - Fix 'dma-ranges' handling in bus controller nodes - Fix handling of initrd start > end - Improve error reporting in of_irq_init() - Taint kernel on DT unittest running - Use strscpy instead of strlcpy - Add a build target, dt_compatible_check, to check for compatible strings used in kernel sources against compatible strings in DT schemas. - Handle DT_SCHEMA_FILES changes when rebuilding DT bindings: - LED bindings for MT6370 PMIC - Convert Mediatek mtk-gce mailbox, MIPS CPU interrupt controller, mt7621 I2C, virtio,pci-iommu, nxp,tda998x, QCom fastrpc, qcom,pdc, and arm,versatile-sysreg to DT schema format - Add nvmem cells to u-boot,env schema - Add more LED_COLOR_ID definitions - Require 'opp-table' uses to be a node - Various schema fixes to match QEMU 'virt' DT usage - Tree wide dropping of redundant 'Device Tree Binding' in schema titles - More (unevaluated|additional)Properties fixes in schema child nodes - Drop various redundant minItems equal to maxItems" * tag 'devicetree-for-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (62 commits) of: base: Shift refcount decrement in of_find_last_cache_level() dt-bindings: leds: Add MediaTek MT6370 flashlight dt-bindings: leds: mt6370: Add MediaTek MT6370 current sink type LED indicator dt-bindings: mailbox: Convert mtk-gce to DT schema of: base: make of_device_compatible_match() accept const device node of: Fix "dma-ranges" handling for bus controllers of: fdt: Remove unused struct fdt_scan_status dt-bindings: display: st,stm32-dsi: Handle data-lanes in DSI port node dt-bindings: timer: Add power-domains for TI timer-dm on K3 dt: Add a check for undocumented compatible strings in kernel kbuild: take into account DT_SCHEMA_FILES changes while checking dtbs dt-bindings: interrupt-controller: migrate MIPS CPU interrupt controller text bindings to YAML dt-bindings: i2c: migrate mt7621 text bindings to YAML dt-bindings: power: gpcv2: correct patternProperties dt-bindings: virtio: Convert virtio,pci-iommu to DT schema dt-bindings: timer: arm,arch_timer: Allow dual compatible string dt-bindings: arm: cpus: Add kryo240 compatible dt-bindings: display: bridge: nxp,tda998x: Convert to json-schema dt-bindings: nvmem: u-boot,env: add basic NVMEM cells dt-bindings: remoteproc: qcom,adsp: enforce smd-edge schema ...
