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"
