[PATCH next 3/3] dts: arm64: mediatek: mt8188: fix audio amplifier reset polarity
From: Catalin Popescu
Date: Thu Jul 03 2025 - 03:51:06 EST
A few MT8188 boards defines a wrong polarity for the audio amplifier's
(TAS2563/2781) reset gpio. This is due to the driver assuming a wrong
polarity so the devicetrees have to configure a wrong polarity for the
audio amplifier to be working. Now, that the driver has been fixed, we
can configure the correct polarity in the devicetrees.
