This basically abandons my earlier attempts and goes back to Takahiro
Akashi's driver. Here is the link to Takahiro's patchset:
https://lore.kernel.org/all/20231005025843.508689-1-takah...
v5: Addresses Andy's cleanups to the driver.
Adrresses Krzysztof's comments about the dt spec file.
And almost all the subsystem prefixes were wrong.
v4: Addressed Andy's comments about kernel-doc
Addressed Rob's comments on the spec file
v3: Forward ported Takahiro's patches and added some fixes ups to make
it work on current kernels.
AKASHI Takahiro (3):
pinctrl: introduce pinctrl_gpio_get_config()
gpio: dt-bindings: Add bindings for pinctrl based generic gpio driver
gpio: gpio-by-pinctrl: add pinctrl based generic GPIO driver
Dan Carpenter (4):
pinctrl: scmi: Add SCMI_PIN_INPUT_VALUE
pinctrl: scmi: Delete PIN_CONFIG_OUTPUT_IMPEDANCE_OHMS support
pinctrl: scmi: ignore PIN_CONFIG_PERSIST_STATE
firmware: arm_scmi: Allow PINCTRL_REQUEST to return EOPNOTSUPP
