Hi all, Investigating the RK3328 GPIO_MUTE pin in the context of boards that use it to control a regulator has highlighted that the audio codec driver currently has some hard-coded implicit control of that pin. Fortunately those boards don't currently enable the audio codec, because it would be pretty terrible if playing audio changed the SD card I/O voltage. This is a first crack at making things better.
