Firmware driver enables APU to communicate to PMUFW(Platform Management Unit)
via ATF by
using SMC instructions. This patchset is adding support for base firmware
driver with query
and clock control APIs. More API support will be added with incremental
patchsets along with
their user driver.
v12:
- Removed clock driver patches from set
- Removed ioctl api support
- Incorporated minor review comments from v11 patch series
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/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:
