Subject: [PATCH v5 0/3] Add ZynqMP pinctrl driver
Date: Thu, 15 Apr 2021 16:43:10 +0530	[thread overview]
Message-ID: <1618485193-5403-1-git-send-email-lakshmi.sai.krishna.potthuri@xilinx.com> (raw)

Add support for Xilinx ZynqMP pinctrl driver and also update
the Xilinx firmware driver to support pinctrl functionality.
This driver queries the pin information from the firmware and
allow configuring the pins as per the request.

changes in v5:
- Used generic property 'power-source' instead of driver specific for
configuring the IO voltages, updated the same in dt-binding.
- Added support to build driver as a module.
- Used error codes returned by the Xilinx firmware instead of shadowing the
error codes in the driver.
- Fixed comments from Andy related to spell checks, NULL checks, explicit
typecast, header inclusion ordering, removing kernel docs for the
obvious ones.

changes in v4:
- Added comment for ignoring the return value for GET_FUNCTION_NAME qid.
- Updated the zynqmp_pinctrl_get_function_name() API prototype to void as
it always returns zero.

changes in v3:
- Fixed binding doc comments from Rob.
- Used 'maxItems' for groups and pins properties.
- Updated commit subject and description to have present tense statements.

changes in v2:
- Use pattern for pin names in yaml file.
- Updated to support multiple groups and pins.
- Added type ref for the vendor specific properties.
- Removed 'schmitt-cmos', instead used common properties.
- Removed macros for drive-strength property.
