On some boards with multiple WSA8840/WSA8845 speakers, the reset (shutdown) GPIO is shared between two speakers. Request it as GPIOD_FLAGS_BIT_NONEXCLUSIVE to allow such configurations.
wsa884x->sd_n = devm_gpiod_get_optional(dev, "powerdown",
GPIOD_OUT_HIGH);
GPIOD_FLAGS_BIT_NONEXCLUSIVE | GPIOD_OUT_HIGH);
How do the speakers coordinate?
