Sean Wang ca071afedb pinctrl: mediatek: remove unused fields in struct mtk_eint_hw
The .name field has been not being used in existent code logic, so
it's better that we remove them all.

Sean Wang e6612a6974 pinctrl: mediatek: use generic EINT register maps for each SoC
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.

Sean Wang e46df235b4 pinctrl: mediatek: refactor EINT related code for all MediaTek pinctrl can fit
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.

Sean Wang ceba43834d pinctrl: mediatek: reuse pinctrl driver for mt7623
mt7623 pinctrl hardware can be compatible with mt2701 driver,
so the patch lets the pinctrl on mt7623 SoC reuse the driver
and deletes those redundant ones.

Biao Huang 148b95eea0 pinctrl: mediatek: Add Pinctrl/GPIO/EINT driver for mt2701

MT2701 have some special pins need an extra setting register
than other ICs, so adding this support to common code.
