From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dmitry Osipenko Subject: [PATCH v1 1/2] dt-bindings: sound: tegra-wm8903: Document new nvidia,headset property Date: Mon, 30 Mar 2020 23:40:10 +0300 Message-ID: <20200330204011.18465-2-digetx@gmail.com> References: <20200330204011.18465-1-digetx@gmail.com> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: In-Reply-To: <20200330204011.18465-1-digetx@gmail.com> Sender: linux-kernel-owner@vger.kernel.org To: Rob Herring , Mark Brown , Jaroslav Kysela , Takashi Iwai , Liam Girdwood , Stephen Warren , Jonathan Hunter Cc: devicetree@vger.kernel.org, linux-tegra@vger.kernel.org, alsa-devel@alsa-project.org, linux-kernel@vger.kernel.org List-Id: linux-tegra@vger.kernel.org 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.
