Merge tag 'devicetree-for-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull DeviceTree updates from Rob Herring:
 "There's a few orphans in the conversion to %pOF printf specifiers
  included here that no one else picked up.

  Summary:

   - Convert more DT code to use of_property_read_* API.

   - Improve DT overlay support when adding multiple overlays

   - Convert printk's to %pOF format specifiers. Most went via subsystem
     trees, but picked up the remaining orphans

   - Correct unittests to use preferred "okay" for "status" property
     value

   - Add a KASLR seed property

   - Vendor prefixes for Mellanox, Theobroma System, Adaptrum, Moxa

   - Fix modalias buffer handling

   - Clean-up of include paths for building dtbs

   - Add bindings for amc6821, isl1208, tsl2x7x, srf02, and srf10
     devices

   - Add nvmem bindings for MediaTek MT7623 and MT7622 SoC

   - Add compatible string for Allwinner H5 Mali-450 GPU

   - Fix links to old OpenFirmware docs with new mirror on
     devicetree.org

   - Remove status property from binding doc examples"
