From 435705e89265dec3c641fe75deb748f05e232e59 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 20 May 2013 11:16:10 -0500 Subject: ASoC: wm8994: Handle LRCLK inversion for WM8958 and WM1811A On WM8958 and WM1811A separate control of the LRCLK inversion bit is available for the DAC and ADC LRCLKs which for compatibility reasons is done in a new register bit. Since writes to each scheme have no effect on parts using the other just always write to both for simplicity.
