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.
