From 5500e3964b8c154dc5af51ebcd7cd4df5d4abfee Mon Sep 17 00:00:00 2001 From: Qiao Zhou Date: Mon, 9 Jul 2012 14:37:33 +0800 Subject: mfd: Add companion chip in 88pm80x in hw design, 800 is mainly for pmic control, while 805 for audio. but there are 3 registers which controls class D speaker property, and they are defined in 800 i2c client domain. so 805 codec driver needs to use 800 i2c client to access class D speaker reg for audio path management. so add this workaround for the purpose to let 805 access 800 i2c in some scenario.
