From 57e41f3fb32a359753a3b2679c2502b2750bf6af Mon Sep 17 00:00:00 2001 From: John Keeping Date: Mon, 9 May 2016 12:24:30 +0100 Subject: [PATCH] ASoC: es8328: Fix ADC format setup The ADCCONTROL4 and DACCONTROL1 registers are similar but not identical, with the DACCONTROL1 having each field starting one bit higher than ADCCONTROL4. Instead of introducing a magic shift, add new constants for the values in ADCCONTROL4 and use a second variable to setup the ADC.
