Subject: [PATCH v1] arm64: dts: qcom: qcm6490-idp: Fix WCD9370 reset GPIO polarity
Date: Fri, 20 Feb 2026 14:32:20 +0530 [thread overview]
Message-ID: <20260220090220.2992193-1-ravi.hothi@oss.qualcomm.com> (raw)
The WCD9370 audio codec reset line on QCM6490 IDP should be active-low, but
the device tree described it as active-high. As a result, the codec is
kept in reset and fails to reset the SoundWire, leading to timeouts
and ASoC card probe failure (-ETIMEDOUT).
Fix the reset GPIO polarity to GPIO_ACTIVE_LOW so the codec can properly
initialize.
Fixes: aa04c298619f ("arm64: dts: qcom: qcm6490-idp: Add WSA8830 speakers and WCD9370 headset codec")
