pinctrl: mediatek: add support for different types of IO pins

2022-05-05T13:29:58Z

There are many pins in an SoC, and register usage may vary by pins. This patch introduces a concept of "io type" and "io type group" to mediatek pinctrl drivers. This can provide different pinconf handlers implementation (eg: "bias-pull-up/down", "driving" and "input-enable") for IO pins that belong to different types. Signed-off-by: Sam Shih

pinctrl: mediatek: introduce multiple memory bases support

2022-05-05T13:29:58Z

Pinctrl design of some mediatek SoC need to access registers that distribute in multiple memory base address. this patch introduce new mechanism in mediatek pinctrl driver to support the chips which have the new design. This patch add a member 'base_calc' in pinctrl private data, and changed original 'base' private data to an array of *iomem. When 'base_calc' attribute is set, it will requests multiplue regs base from the DT, if 'base_calc' attribute is not set, it only use legacy way to request single reg resource from the DT.

pinctrl: mediatek: rewrite mtk_pinconf_set and related functions

2022-05-05T13:29:57Z

There are many pins in a SoCs, and different pin may belong to different "io_type", For example: some pins of MT7622 belongs to "io_type A", the other belongs to "io_type B", and pinctrl "V0" means handle pinconf via "io_type A" or "io_type B", so SoCs that contain "io_type A" and "io_type B" pins, use "V0" in pinctrl driver. This patch separates the implementation of register operations (e.g: "bias-pull-up/down", "driving" and "input-enable") into different functions, and lets the original V0/V1 ops to call the new functions.

pinctrl: mt7629: add jtag function and pin group

2021-03-20T20:24:27Z

The EPHY LEDs of mt7629 can be used as JTAG. This patch adds the jtag pin group to the pinctrl driver. Signed-off-by: Weijie Gao

pinctrl: mediatek: do not probe gpio driver if not enabled

2021-03-20T20:24:27Z

The mtk pinctrl driver is a combination driver with support for both pinctrl and gpio. When this driver is used in SPL, gpio support may not be enabled, and this will result in a compilation error. To fix this, macros are added to make sure gpio related code will only be compiled when gpio support is enabled. Signed-off-by: Weijie Gao

pinctrl: mediatek: add get_pin_muxing ops for mediatek pinctrl

pinctrl: mediatek: fix wrong assignment in mtk_get_pin_name

2021-03-20T20:24:27Z

This is a bug fix for mtk pinctrl common part. Appearently pins should be used instead of grps in mtk_get_pin_name(). Signed-off-by: Sam Shih

pinctrl: mediatek: correct error handling

2021-01-18T20:23:06Z

If no GPIO controller is found, the return value should not depend on a random value on the stack. Initialize variable ret. The problem was indicated by cppcheck. Signed-off-by: Heinrich Schuchardt Acked-by: Chunfeng Yun
