Merge tag 'devicetree-for-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull Devicetree updates from Rob Herring:
 "The biggest highlight here is the start of using json-schema for DT
  bindings. Being able to validate bindings has been discussed for years
  with little progress.

   - Initial support for DT bindings using json-schema language. This is
     the start of converting DT bindings from free-form text to a
     structured format.

   - Reworking of initrd address initialization. This moves to using the
     phys address instead of virt addr in the DT parsing code. This
     rework was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary
     rebuilding of lots of files.

   - Fix stale phandle entries in phandle cache

   - DT overlay validation improvements. This exposed several memory
     leak bugs which have been fixed.

   - Use node name and device_type helper functions in DT code

   - Last remaining conversions to using %pOFn printk specifier instead
     of device_node.name directly

   - Create new common RTC binding doc and move all trivial RTC devices
     out of trivial-devices.txt.

   - New bindings for Freescale MAG3110 magnetometer, Cadence Sierra
     PHY, and Xen shared memory

   - Update dtc to upstream version v1.4.7-57-gf267e674d145"
