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

pinctrl: mediatek: Add Pinctrl/GPIO/EINT driver for mt2701

2016-01-28T10:12:03Z

Add mt2701 support using mediatek common pinctrl driver. MT2701 have some special pins need an extra setting register than other ICs, so adding this support to common code. Signed-off-by: Biao Huang Acked-by: Yingjoe Chen Signed-off-by: Linus Walleij

pinctrl: mediatek: add OF dependency to MT6397

2015-05-20T07:11:23Z

X86_64 allmodconfig screams like so: warning: (PINCTRL_MT6397) selects PINCTRL_MTK_COMMON which has unmet direct dependencies (PINCTRL && (ARCH_MEDIATEK || COMPILE_TEST) && OF) So add OF to dependencies to shut up this warning. Cc: Hongzhou Yang Signed-off-by: Linus Walleij

pinctrl: mediatek: Add Pinctrl/GPIO driver for mt6397.

2015-05-19T09:16:17Z

Add mt6397 support using mediatek common pinctrl driver. mt6397 is a PMIC, and pinctrl/GPIO is part of 6397 chip. Pinctrl/GPIO driver should obtain regmap from PMIC, so adding this support to common code. Also, mt6397 is no need to support interrupt controller, so changing common code to skip it.
