On Qualcomm platforms such as QCS6490-RB3Gen2, the WSA883x speaker amplifiers share the SD_N GPIO line between two speakers, thus requires coordinated control when asserting the GPIO. Linux supports shared GPIO handling via the "reset-gpios" property, which can be used to specify either the powerdown or reset GPIOs.
