Linux supports handling shared GPIO lines through "reset-gpios" property, thus allow specifying either powerdown or reset GPIOs (these are the same). Cc: Bartosz Golaszewski Cc: Sean Anderson Acked-by: Rob Herring Signed-off-by: Krzysztof Kozlowski --- Resending because reset part of the patchset was applied, so this can go independently via ASoC. https://lore.kernel.org/all/38fda6619769da7240517982adfe734cb653ff5e.camel@pengutronix.de/ Changes in v6 ============= 1.
