Add EINT support to MT7622 SoC and the support is made as just an option to MT7622 pinctrl. Signed-off-by: Sean Wang Signed-off-by: Linus Walleij

pinctrl: mediatek: refactor EINT related code for all MediaTek pinctrl can fit

2018-05-24T07:37:21Z

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.

pinctrl: mediatek: add pinctrl driver for MT7622 SoC

2017-12-20T07:49:41Z

Add support for pinctrl on MT7622 SoC. The IO core found on the SoC has the registers for pinctrl, pinconf and gpio mixed up in the same register range. However, the IO core for the MT7622 SoC is completely distinct from anyone of previous MediaTek SoCs which already had support, such as the hardware internal, register address map and register detailed definition for each pin. Therefore, instead, the driver is being newly implemented by reusing generic methods provided from the core layer with GENERIC_PINCONF, GENERIC_PINCTRL_GROUPS, and GENERIC_PINMUX_FUNCTIONS for the sake of code simplicity and rid of superfluous code. Where the function of pins determined by groups is utilized in this driver which can help developers less confused with what combinations of pins effective on the SoC and even reducing the mistakes during the integration of those relevant boards. As the gpio_chip handling is also only a few lines, the driver also implements the gpio functionality directly through GPIOLIB.

pinctrl: mediatek: cleanup for placing all drivers under the menu

2017-12-20T07:47:56Z

Since lots of MediaTek drivers had been added, it seems slightly better for that adding cleanup for placing MediaTek pinctrl drivers under the independent menu as other kinds of drivers usually was done. Signed-off-by: Sean Wang Reviewed-by: Biao Huang Signed-off-by: Linus Walleij

pinctrl: mediatek: reuse pinctrl driver for mt7623

2017-05-22T08:39:25Z

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. Signed-off-by: Sean Wang Acked-by: John Crispin Reviewed-by: Matthias Brugger Signed-off-by: Linus Walleij

pinctrl: mediatek: Use real dependencies

2017-01-26T15:26:50Z

Do not hide pinctrl drivers for Mediatek platforms using conditionals. Doing so actually leaves the symbols present (but always disabled) on all other platforms, which is confusing and inefficient. Better use real dependencies so that the symbols do not exist at all on platforms where they are not relevant.

pinctrl: mediatek: guard sub-directory with CONFIG_PINCTRL_MTK

2016-02-13T22:34:19Z

CONFIG_PINCTRL_MTK is more suitable than CONFIG_ARCH_MEDIATEK to guard the drivers/pinctrl/mediatek/ directory. (I renamed CONFIG_PINCTRL_MTK_COMMON to CONFIG_PINCTRL_MTK.) This allows COMPILE_TEST to descend into drivers/pinctrl/mediatek without CONFIG_ARCH_MEDIATEK define. Signed-off-by: Masahiro Yamada Signed-off-by: Linus Walleij
