Subject: [PATCH v5 1/2] ASoC: dt-bindings: qcom,wsa8830: Add reset-gpios for shared line
Date: Fri, 15 Aug 2025 22:53:52 +0530	[thread overview]
Message-ID: <20250815172353.2430981-2-mohammad.rafi.shaik@oss.qualcomm.com> (raw)
In-Reply-To: <20250815172353.2430981-1-mohammad.rafi.shaik@oss.qualcomm.com>

On Qualcomm platforms such as QCS6490-RB3Gen2, the WSA883x speaker
amplifiers share the SD_N GPIO line between two speakers, thus
requires coordinated control when asserting the GPIO. Linux supports
shared GPIO handling via the "reset-gpios" property, which can be
used to specify either the powerdown or reset GPIOs.
