Hongzhou Yang c445cac307 pinctrl: mediatek: fix build error
Due to pinconf_generic_parse_dt_config() API changes in pinctrl
devel branch, add one parameter to fix build error.

Also fix warning:
drivers/pinctrl/mediatek/pinctrl-mtk-common.c:718:3: warning:
too many arguments for format [-Wformat-extra-args]
      dev_err(&pdev->dev, "only support pins-are-numbered format\n", ret);
      ^

by removing extra parameter when calling dev_err in mtk_pctrl_init.

Yingjoe Chen 3221f40b76 pinctrl: mediatek: emulate GPIO interrupt on both-edges
MTK EINT does not support generating interrupt on both edges.
Emulate this by changing edge polarity while enable irq,
set types and interrupt handling. This follows an example of
drivers/gpio/gpio-mxc.c.

Hongzhou Yang 30f010f5c4 arm64: mediatek: Add Pinctrl/GPIO/EINT driver for mt8173.
Add mt8173 support using mediatek common pinctrl driver.
MT8173 have a different ies_smt setting register than mt8135,
so adding this support to common code.

Hongzhou Yang a6df410d42 pinctrl: mediatek: Add Pinctrl/GPIO driver for mt8135.
The mediatek SoCs have GPIO controller that handle both the muxing and GPIOs.

The GPIO controller have pinmux, pull enable, pull select, direction and output high/low control.

This driver include common driver and mt8135 part.
The common driver include the pinctrl driver and GPIO driver.
The mt8135 part contain its special device data.
