The pinctrl-at91 driver already exports an at91_mux_pin function, but that one is only usable after driver probe. Instead, provide an at91_mux_pio_pin function, which can be used at all times. This is similar to the already existing at91_mux_pio3_pin function Signed-off-by: Sam Ravnborg --- arch/arm/mach-at91/include/mach/gpio.h | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) diff --git a/arch/arm/mach-at91/include/mach/gpio.h b/arch/arm/mach-at91/include/mach/gpio.h index ddd6971e3..7f84f41e5 100644 --- a/arch/arm/mach-at91/include/mach/gpio.h +++ b/arch/arm/mach-at91/include/mach/gpio.h @@ -151,6 +151,31 @@ static inline int at91_mux_gpio_get(void __iomem *pio, unsigned mask) return (pdsr & mask) != 0; } +static inline void at91_mux_pio_pin(void __iomem *pio, unsigned mask, + enum at91_mux mux, int gpio_state) +{ + at91_mux_disable_interrupt(pio, mask); + + switch(mux) { + case AT91_MUX_GPIO: + at91_mux_gpio_enable(pio, mask); + break; + case AT91_MUX_PERIPH_A: + at91_mux_set_A_periph(pio, mask); + break; + case AT91_MUX_PERIPH_B: + at91_mux_set_B_periph(pio, mask); + break; + default: + /* ignore everything else */ + break; + } + if (mux != AT91_MUX_GPIO) + at91_mux_gpio_disable(pio, mask); + + at91_mux_set_pullup(pio, mask, gpio_state & GPIO_PULL_UP); +} + static inline void at91_mux_pio3_pin(void __iomem *pio, unsigned mask, enum at91_mux mux, int gpio_state) { -- 2.34.1
