2018-05-24pinctrl: mediatek: remove unused fields in struct mtk_eint_hwSean Wang
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 Wang
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 Wang
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.

2017-05-22pinctrl: mediatek: reuse pinctrl driver for mt7623Sean Wang
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.
