Subject: [PATCH v3 2/2] arm64: dts: imx8mm-evk: Enable audio codec wm8524
Date: Wed, 24 Apr 2019 15:04:14 +0000	[thread overview]
Message-ID: <20190424150350.7963-3-daniel.baluta@nxp.com> (raw)
In-Reply-To: <20190424150350.7963-1-daniel.baluta@nxp.com>

i.MX8MM has one wm8524 audio codec connected with
SAI3 digital audio interface.

This patch uses simple-card machine driver in order
to enable wm8524 codec.

We need to set:
	* SAI3 pinctrl configuration
	* codec reset gpio pinctrl configuration
	* clock hierarchy
	* codec node
	* simple-card configuration
