From 6f69661f6ebe44dbe5e5dee67278266199bcbd32 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Wed, 20 Mar 2019 22:41:56 +0100 Subject: [PATCH] ASoC: cs4270: Set auto-increment bit for register writes [ Upstream commit f0f2338a9cfaf71db895fa989ea7234e8a9b471d ] The CS4270 does not by default increment the register address on consecutive writes. During normal operation it doesn't matter as all register accesses are done individually. At resume time after suspend, however, the regcache code gathers the biggest possible block of registers to sync and sends them one on one go. To fix this, set the INCR bit in all cases.
