[PATCH 0/7] pinctrl: mediatek: Fixes and minor improvements

From: Chen-Yu Tsai
Date: Tue Jan 11 2022 - 06:22:52 EST


Hi everyone,

Here are some fixes and minor improvements to generic pinconf and the
Mediatek Paris pinctrl driver.

Patch 1 makes the generic pinconf library print out arguments for
PIN_CONFIG_BIAS_PULL_* in debugfs.

Patch 2 fixes bogus readback of PIN_CONFIG_BIAS_DISABLE being always
present.

Patch 3 fixes the type of the "argument" argument in mtk_pinconf_get().
This was erroneously typed as an enum when it should have been u32.

Patch 4 fixes the pingroup config state readback to actually do
readback.

Patch 5 drops an extra newline in the pinconf debugfs output.

Patch 6 cleans up the debugfs output, skipping the custom hardware state
output on the virtual GPIOs, which have no corresponding hardware.

Patch 7 adds support for PIN_CONFIG_DRIVE_STRENGTH_UA (drive-strength-uA)
to the Mediatek Paris pinctrl library. The goal is to replace the vendor
specific "mtk,drive-strength-adv" property with the generic one.

Later on we might want to deprecate "mtk,drive-strength-adv".

Please have a look.


Regards
ChenYu
