In Rockchip RK3328, the output only GPIO_MUTE pin, originally for codec mute control, can also be used for general purpose. It is manipulated by the GRF_SOC_CON10 register in GRF. Aside from the GPIO_MUTE pin, the HDMI pins can also be set in the same way. Currently this GRF GPIO controller only supports the mute pin. If needed in the future, the HDMI pins support can also be added. Signed-off-by:
