Subject: [PATCH AUTOSEL 6.18] arm64: dts: qcom: qcm6490-idp: Fix WCD9370 reset GPIO polarity
Date: Mon, 20 Apr 2026 09:20:50 -0400	[thread overview]
Message-ID: <20260420132314.1023554-256-sashal@kernel.org> (raw)
In-Reply-To: <20260420132314.1023554-1-sashal@kernel.org>

From: Ravi Hothi <ravi.hothi@oss.qualcomm.com>

[ Upstream commit b7df21c59739cceb7b866c6c5e8a6ba03875ab71 ]

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.
