2022-03-17pinctrl: mediatek: common-v1: Commonize spec_ies_smt_set callbackAngeloGioacchino Del Regno
All of the MediaTek pinctrl drivers registering with pinctrl-mtk-common that are offering a .spec_ies_smt_set() callback are declaring their own function which is doing exactly the same on all drivers: calling mtk_pconf_spec_set_ies_smt_range() with their struct and a simple check. Commonize this callback by adding the ies and smt structure pointers to struct mtk_pinctrl_devdata and changing the callback signature to take it. Removing the callback and checking for the existance of the spec_smt and/or spec_ies data would allow us to staticize the function mtk_pconf_spec_set_ies_smt_range(), but this solution was avoided as to keep flexibility, as some SoCs may need to perform a very different operation compared to what this commonized function is doing.

For all of the drivers that don't require passing a struct regmap pointer from a parent device, simplify the probe mechanism by assigning the required structure as match data and use mtk_pctrl_common_probe() as their probe function.

2022-03-15pinctrl: mediatek: paris: Support generic PIN_CONFIG_DRIVE_STRENGTH_UAChen-Yu Tsai
Some of the MediaTek chips that utilize the Paris pinctrl driver library support a lower drive strength (<= 1mA) than the standard drive strength settings (2~16 mA) on certain pins. This was previously supported by the custom MTK_PIN_CONFIG_DRV_ADV parameter along with the "mediatek,drive-strength-adv" device tree property. The drive strength values for this hardware are 125, 250, 500, and 1000 mA, and can be readily described by the existing "drive-strength-microamp" property, which then gets parsed by the generic pinconf library into the parameter PIN_CONFIG_DRIVE_STRENGTH_UA. Add support for PIN_CONFIG_DRIVE_STRENGTH_UA while keeping the old custom parameter around for backward compatibility.

2022-03-15pinctrl: mediatek: paris: Rework mtk_pinconf_{get,set} switch/case logicChen-Yu Tsai
The current code deals with optional features by testing for the function pointers and returning -ENOTSUPP if it is not valid. This is done for multiple pin config settings and results in the code that handles the supporting cases to get indented by one level. This is aggrevated by the fact that some features require another level of conditionals. Instead of assigning the same error code in all unsupported optional feature cases, simply have that error code as the default, and break out of the switch/case block whenever a feature is unsupported, or an error is returned. This reduces indentation by one level for the useful code. Also replace the goto statements with break statements. The result is the same, as the gotos simply exit the switch/case block, which can also be achieved with a break statement. With the latter the intent is clear and easier to understand.
