From 18790b1b514a202bae2863a4206b731d95302c85 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 10 Sep 2020 15:41:09 +0300 Subject: [PATCH] ASoC: dt-bindings: ti, j721e-cpb-audio: Document support for j7200-cpb 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.
