2022-03-17pinctrl: mediatek: common-v1: Commonize spec_ies_smt_set callbackAngeloGioacchino Del Regno1-14/+5
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.

2022-03-17pinctrl: mediatek: common-v1: Commonize spec_pupd callbackAngeloGioacchino Del Regno1-11/+3
Reduce code size and duplication by using a common spec_pupd callback, which is possible to use on all of the pinctrl drivers that are using the v1 pinctrl-mtk-common code, with the exception of mt8135, which has a different handling compared to the others. Since the callback function signature was changed, this had to be propagated to pinctrl-mt8135's spec_pull_set().

2022-03-17pinctrl: mediatek: common-v1: Use common probe functionAngeloGioacchino Del Regno1-9/+2
Most of the mediatek pinctrl drivers are calling mtk_pctrl_init() and passing only a pointer to struct mtk_pinctrl_devdata, as the regmap handle it passed from device-tree, with the exception of mt6397. 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. While at it, also collapse the of_device_id entries to a single line, as they all fit in max 83 columns, which is acceptable.

2021-05-27pinctrl: mediatek: don't hardcode mode encoding in common codeFabien Parent1-0/+3
MT8365 encode the pins mode differently than other MTK pinctrl drivers that use the PINCTRL_MTK common code. Add 3 new fields in mtk_pinctrl_devdata in order to store how pin modes are encoded into the register. At the same time update all the pinctrl driver that depends on CONFIG_PINCTRL_MTK.

The .name field has been not being used in existent code logic, so it's better that we remove them all. Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2018-05-24pinctrl: mediatek: use generic EINT register maps for each SoCSean Wang1-20/+0
So far, EINT on each SoC all used exactly identical register map and thus it's better that we apply generic register map already supported in EINT library and stop copy-n-pasting the same data block and filling into its platform data.

2018-05-24pinctrl: mediatek: refactor EINT related code for all MediaTek pinctrl can fitSean Wang1-5/+7
This patch is in preparation for adding EINT support to MT7622 pinctrl, and the refactoring doesn't alter any existent logic. A reason we have to refactor EINT code pieces into a generic way is that currently, they're tightly coupled with a certain type of MediaTek pinctrl would cause a grown in a very bad way as there is different types of pinctrl devices getting to join. Therefore, it is an essential or urgent thing that EINT code pieces are refactored to eliminate any dependencies across GPIO and EINT as possible. Additional structure mtk_eint_[xt, hw, regs] are being introduced for indicating how maps being designed between GPIO and EINT hw number, how to set and get GPIO state for a certain EINT pin, what characteristic on a EINT device is present on various SoCs.
