Subject: [PATCH 1/2] ASoC: dt-bindings: ti,j721e-cpb-audio: Document support for j7200-cpb
Date: Thu, 10 Sep 2020 10:54:32 +0300 [thread overview]
Message-ID: <20200910075433.26718-2-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <20200910075433.26718-1-peter.ujfalusi@ti.com>
j721e or j7200 SOM can be attached to the same Common Processor Board (CPB)
With the j7200 SOM only the 48KHz family parent clock is available and
McASP0 is used for the audio.
