Subject: [PATCH v1 1/2] dt-bindings: sound: tegra-wm8903: Document new nvidia,headset property
Date: Mon, 30 Mar 2020 23:40:10 +0300 [thread overview]
Message-ID: <20200330204011.18465-2-digetx@gmail.com> (raw)
In-Reply-To: <20200330204011.18465-1-digetx@gmail.com>
Some devices have a 4-pin headset jack instead of 3-pin microphone jack.
The new boolean nvidia,headset property tells that the Mic Jack represents
the state of a headset microphone. This additional hardware description is
needed because microphone detection procedure differs in a case of a 4-pin
jack from a 3-pin jack.
