Subject: [PATCH v6 00/11] drivers: Introduce firmware dnd clock river for ZynqMP core

This patchset is adding communication layer with firmware and clock driver who uses 
those APIs to communicate with PMU.
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.
This patchset adds CCF compliant clock driver for ZynqMP.Clock driver queries supported clock information from 
firmware and regiters pll and output clocks with CCF.

v6:
 - Broke patch series to have base FW driver and Clock driver user
 - Incorporated code review comments from last FW and Clock driver patch series. Discussed below:
	https://patchwork.kernel.org/patch/10230759/
	https://patchwork.kernel.org/patch/10250047/

v5:
 - Added ATF version check support
 - Updated some functions to be static 
 - Minor function name corrections

v4:
 - Changed clock setrate/getrate API prototype to support 64 bit rate
 - Defined macros for get_node_status return values
 - Moved DT node as a child of firmware
 - Changed debugfs APIs to return data to debugfs buffer instead of dumping to kernel log
 - Minor changes to incorporate other review comments from v3 patch series

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:
