Subject: [PATCH] pinctrl: mediatek: extend pinctrl-moore to support new bias
|
|
functions
|
|
|
|
Commit fb34a9ae383a ("pinctrl: mediatek: support rsel feature")
|
|
introduced SoC specify 'pull_type' attribute to mtk_pinconf_bias_set_combo
|
|
and mtk_pinconf_bias_get_combo, and make the functions able to support
|
|
almost all Mediatek SoCs that use pinctrl-mtk-common-v2.c.
|
|
|
|
This patch enables pinctrl_moore to support these functions.
