Subject: [PATCH v2 1/6] ARM: dts: omap2420-n810: Enable McBSP2 for audio
Date: Fri, 27 Apr 2018 11:17:10 +0300 [thread overview]
Message-ID: <20180427081715.28791-2-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <20180427081715.28791-1-peter.ujfalusi@ti.com>
McBSP2 is used with the tlv320aic33 codec for audio.
Pin mux change is needed to get the needed signals in/out from the SoC.
