- Ethernet, i2c, and USB support are now enabled by default
- The clock driver gets some bug fixes and cleanup
- Invalid FDTs are now properly detected in board_fdt_blob_setup().
- The pinctrl driver gains preparatory support for per-pin function
  muxes.
- Support is added for two generations of Qualcomm HighSpeed USB PHY
- A power domain driver is added for the Globall Distributed Switch
  Controllers on the GCC hardware block.
- SDM845 gains USB host mode support.
- OF_LIVE is enabled by default for Qualcomm platforms
- Some U-Boot devicetree compatibility fixups are added during init to
  improve compatbility with upstream DT.

* OF_LIVE devicetree fixup.
*
* This file implements runtime fixups for Qualcomm DT to improve
* compatibility with U-Boot. This includes adjusting the USB nodes
* to only use USB high-speed, as well as remapping volume buttons
* to behave as up/down for navigating U-Boot.
*
* We use OF_LIVE for this rather than early FDT fixup for a couple
* of reasons: it has a much nicer API, is most likely more efficient,
* and our changes are only applied to U-Boot. This allows us to use a
* DT designed for Linux, run U-Boot with a modified version, and then
* boot Linux with the original FDT.
