Linus Torvalds 8c94764515 Merge tag 'devicetree-fixes-for-5.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree fixes from Rob Herring:

 - Cleanups on properties with standard unit suffixes

 - Fix overwriting dma_range_map if there's no 'dma-ranges' property

 - Fix a bug when creating a /chosen node from ARM ATAGs

 - Add missing properties for TI j721e USB binding

 - Several doc reference updates due to DT schema conversions

* tag 'devicetree-fixes-for-5.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux:
  dt-bindings: Cleanup standard unit properties
  of/device: Update dma_range_map only when dev has valid dma-ranges
  ARM: zImage: atags_to_fdt: Fix node names on added root nodes
  dt-bindings: usb: j721e: add ranges and dma-coherent props
  dt-bindings:iio:adc: update adc.yaml reference
  dt-bindings: memory: mediatek: update mediatek,smi-larb.yaml references
