[PATCH v1 1/1] pinctrl: mediatek: remove log message in mtk_hw_pin_field_lookup

From: Light Hsieh Originally, mtk_hw_pin_field_lookup() print log message in 2 conditions: 1. when soc does not support target property 2. when target pin does not support target property Now, mtk_hw_pin_field_lookup() does not print log message according to the following rationale: 1. Users of

[PATCH v1 1/1] pinctrl: mediatek: refine mtk_pmx_get_funcs_cnt()

From: Light Hsieh Refine implementation of mtk_pmx_get_funcs_cnt(). The original implementation always return ARRAY_SIZE(mtk_gpio_functions) which is 16. However, MT6765/MT6779 only support 8 functions per GPIO pin. So returning 16 is improper. The new implementation check member nfuncs of struc

[PATCH v1 1/2] pinctrl: mediatek: support access registers without race-condition

From: Light Hsieh Some MediaTek SOC provide more control registers other than value register. Generanll, a value register need read-modify-write is at offset 0x0. A corresponding SET register is at offset 0xXXX4. Write 1s' to some bits of SET register will set same bits in value reg
