pinctrl: mediatek: common-v1: Commonize spec_ies_smt_set callback 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.

Since the callback function signature was changed, this had to be propagated to pinctrl-mt8135's spec_pull_set().

pinctrl: mediatek: common-v1: Commonize spec_pupd callback 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().

pinctrl: mediatek: common-v1: Commonize spec_ies_smt_set callback 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.

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.

pinctrl: mediatek: Fix EINT pins input debounce time configuration The External Interrupt Controller (EINTC) on all of the supported MediaTek SoCs does support input debouncing, but not all of them index the debounce time values (DBNC_SETTING registers) the same way. Before this change, in some cases, as an example, requesting a debounce time of 16 milliseconds would mistakenly set the relative DBNC_SETTING register to 0x2, resulting in a way shorter debounce time of 500uS. To fix the aforementioned issue, define three different debounce_time arrays, reflecting the correct register index for each value and for each register index variant, and make sure that each SoC pinctrl driver uses the right one.
