+Subject: [PATCH 226/752] ASoC: davinci: mcasp: Remove redundant
+ num-serializer DT parameter
+
+The serial-dir array gives this information so there is no need to have the
+num-serializer property in DT description.
+Just ignore the property in the driver the DTS files can be updated
+separately without regression.
+Update the documentation at the same time for davinci-mcasp
