H A D | pinctrl-mt8183.c | diff cafe19db7751269bf6b4dd2148cbfa9fbe91d651 Wed Jan 22 07:53:13 CET 2020 Light Hsieh <light.hsieh@mediatek.com> pinctrl: mediatek: Backward compatible to previous Mediatek's bias-pull usage
Refine mtk_pinconf_set()/mtk_pinconf_get() for backward compatibility to previous MediaTek's bias-pull usage. In PINCTRL_MTK that use pinctrl-mtk-common.c, bias-pull setting for pins with 2 pull resistors can be specified as value for bias-pull-up and bias-pull-down. For example: bias-pull-up = <MTK_PUPD_SET_R1R0_00>; bias-pull-up = <MTK_PUPD_SET_R1R0_01>; bias-pull-up = <MTK_PUPD_SET_R1R0_10>; bias-pull-up = <MTK_PUPD_SET_R1R0_11>; bias-pull-down = <MTK_PUPD_SET_R1R0_00>; bias-pull-down = <MTK_PUPD_SET_R1R0_01>; bias-pull-down = <MTK_PUPD_SET_R1R0_10>; bias-pull-down = <MTK_PUPD_SET_R1R0_11>;
On the other hand, PINCTRL_MTK_PARIS use customized properties "mediatek,pull-up-adv" and "mediatek,pull-down-adv" to specify bias-pull setting for pins with 2 pull resistors. This introduce in-compatibility in device tree and increase porting effort to MediaTek's customer that had already used PINCTRL_MTK version. Besides, if customers are not aware of this change and still write devicetree for PINCTRL_MTK version, they may encounter runtime failure with pinctrl and spent time to debug.
This patch adds backward compatible to previous MediaTek's bias-pull usage so that Mediatek's customer need not use a new devicetree property name. The rationale is that: changing driver implementation had better leave interface unchanged.
