> 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.

> v11:
>  - Removed "Reveiwed-by:Stephen Boyd" tag from firmware binding
>  - Updated clock and firmware driver to use probe method instead of init
>  - Marked PMU payload arguments with __le32 for proper endienness code
> 
> v10:

> v9:
>  - Fixed minor typo comments
> 
> v8:
>  - Corrected typo in clk Kconfig
> 
> v7:
>  - Removed xilinx specific clock debugfs API support
>  - Added reviewed-by tags for FW and clock bindings
>  - Updated clock node name to clock-controller
> 
> v6:
>  - Broke patch series to have base FW driver and Clock driver user
>  - Incorporated code review comments from last FW and Clock driver patch

> 	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:
