From 4b8ab8a7761fe2ba1c4e741703a848cb8f390f79 Mon Sep 17 00:00:00 2001 From: Dan Murphy Date: Fri, 18 Sep 2020 14:05:43 -0500 Subject: ASoC: tas2770: Fix required DT properties in the code The devicetree binding indicates that the ti,asi-format, ti,imon-slot-no and ti,vmon-slot-no are not required but the driver requires them or it fails to probe. Honor the binding and allow these entries to be optional and set the corresponding values to the default values for each as defined in the data sheet.
