Subject: [PATCH v6 4/4] arm64: dts: imx8mq-evk: Enable audio codec wm8952
Date: Fri, 8 Mar 2019 12:02:28 +0000 [thread overview]
Message-ID: <20190308120141.3698-5-daniel.baluta@nxp.com> (raw)
In-Reply-To: <20190308120141.3698-1-daniel.baluta@nxp.com>
The main Audio DAC used on the EVK board is wm8952.
The EVK provides the MCLK to wm8952.
Digital interface is SAI2 which includes three signals:
SYNC_CLK, BCLK and DACDAT.
This patch sets:
* SAI2 pinctrl configuration
* clock hierarchy
* wm8960 codec
Then uses simple-card machine driver to connect them
into a sound card.
