ARM: dts: imx51-zii-rdu1: Do not specify "power-gpio" for hpa1 (79da07de) · Commits · 戴 / test

TPA6130A2 SD pin on RDU1 is not really controlled by SoC and instead is only meant to notify the system that audio was "muted" by external actors. To accommodate that, drop "power-gpio" property of hpa1 node as well as specify a name for that GPIO so that userspace can access it. Signed-off-by:
