Merge tag 'devicetree-for-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree updates from Rob Herring:
 "DT core:

   - Sync dtc/libfdt with upstream v1.7.2-62-ga26ef6400bd8

   - Add a for_each_compatible_node_scoped() loop and convert users in
     cpufreq, dmaengine, clk, cdx, powerpc and Arm

   - Simplify of/platform.c with scoped loop helpers

   - Add fw_devlink tracking for "mmc-pwrseq"

   - Optimize fw_devlink callback code size for pinctrl-N properties

   - Replace strcmp_suffix() with strends()

  DT bindings:

   - Support building single binding targets

   - Convert google,goldfish-fb, cznic,turris-mox-rwtm, ti,prm-inst

   - Add bindings for Freescale AVIC, Realtek RTD1xxx system
     controllers, Microchip 25AA010A EEPROM, OnSemi FIN3385, IEI
     WT61P803 PUZZLE, Delta Electronics DPS-800-AB power supply,
     Infineon IR35221 Digital Multi-phase Controller, Infineon PXE1610
     Digital Dual Output 6+1 VR12.5 & VR13 CPU Controller,
     socionext,uniphier-smpctrl, and xlnx,zynqmp-firmware

   - Lots of trivial binding fixes to address warnings in DTS files.
     These are mostly for arm64 platforms which is getting closer to be
     warning free. Some public shaming has helped.

   - Fix I2C bus node names in examples

   - Drop obsolete brcm,vulcan-soc binding

   - Drop unreferenced binding headers"
