> Subject: [PATCH v11 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.
>
> 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:
> - Incorporated code review comments from v9 patch series. Discussed below:
> https://patchwork.kernel.org/patch/10478575/

> https://patchwork.kernel.org/patch/10478461/
> https://patchwork.kernel.org/patch/10478463/
>
> 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
> 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:
