From 1427e660b49e87cd842dba94158b0fc73030c17e Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Fri, 18 Oct 2013 18:37:46 +0300 Subject: 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.
