pinctrl: rockchip: Add pinctrl support for rk3308

2019-12-05T16:06:23Z

An iomux register contains 8 pins, each of which is represented by 2 bits, but the register offset is 0x8. For example, GRF_GPIO0A_IOMUX offset is 0x0, but GRF_GPIO0B_IOMUX offset is 0x8, the offset 0x4 is reserved. So add a type IOMUX_8WIDTH_2BIT to calculate offset.

pinctrl: rockchip: Also move common set_schmitter func into per Soc file

2019-05-08T09:34:12Z

Only some Soc need Schmitter feature, so move the implementation into their own files. Signed-off-by: David Wu Signed-off-by: Kever Yang

pinctrl: rockchip: Clean the unused type and label

2019-05-08T09:34:12Z

As the mux/pull/drive feature implement at own file, the type and label are not necessary. Signed-off-by: David Wu Signed-off-by: Kever Yang

pinctrl: rockchip: Special treatment for RK3288 gpio0 pins' pull

2019-05-08T09:34:12Z

RK3288 pmu_gpio0 pull setting have no higher 16 writing corresponding bits, need to read before write the register. Signed-off-by: David Wu Signed-off-by: Kever Yang

pinctrl: rockchip: Split the common set_pull() func into per Soc

pinctrl: rockchip: Split the common set_mux() into per Soc

2019-05-08T09:34:12Z

Such as rk3288's pins of pmu_gpio0 are a special feature, which have no higher 16 writing corresponding bits, use common set_mux() func would introduce more code, so implement their set_mux() in each Soc's own file to reduce the size of code. Signed-off-by: David Wu Signed-off-by: Kever Yang
