Subject: [PATCH] ARM: dts: imx7d-sdb: Add notes for audio sound card
Date:   Thu, 23 Jul 2020 13:43:36 +0800
Message-Id: <1595483016-8822-1-git-send-email-shengjiu.wang@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Configure the SAI device node, configure audio clock
and pinctrl.

Enable the audio sound card, which use the SAI1 and
wm8960, and enable headphone detection.
