Subject: [PATCH v4 2/2] arm64: dts: imx8mm-evk: Enable audio codec wm8524
Date: Tue, 4 Jun 2019 20:32:57 +0800 [thread overview]
Message-ID: <20190604123257.2920-3-daniel.baluta@nxp.com> (raw)
In-Reply-To: <20190604123257.2920-1-daniel.baluta@nxp.com>
From: Daniel Baluta <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
