Subject: [PATCH] pinctrl: mediatek: Fix fallback call path
Date: Mon, 28 Dec 2020 17:04:25 +0800 [thread overview]
Message-ID: <20201228090425.2130569-1-hsinyi@chromium.org> (raw)
Some SoCs, eg. mt8183, are using a pinconfig operation bias_set_combo.
The fallback path in mtk_pinconf_adv_pull_set() should also try this
operation.
Fixes: cafe19db7751 ("pinctrl: mediatek: Backward compatible to previous Mediatek's bias-pull usage")
Signed-off-by: Hsin-Yi Wang <hsinyi@chromium.org>
