Introduce firmware driver for ZynqMP core.
This patchset is adding communication layer with firmware.
Firmware driver provides an interface to firmware APIs.
Interface APIs can be used by any driver to communicate to
PMUFW(Platform Management Unit). All requests go through ATF.
v3:
- added some fixes to firmware-ggs.c
- updated pinmux get/set function argument names to specify function id
instead of node id
- added new pinctrl query macros
- incorporated review comments from v2 patch series
v2:
- change SPDX-License-Identifier license text style
- split patch into multiple patches
- Updated copyrights
- Added ABI documentation
- incorporated logical review comments from previuos patch. Discussed below:
