From 0d43b3468871f5d5194edfe7052b6a49691eb6fd Mon Sep 17 00:00:00 2001 From: Matt Ranostay Date: Sat, 13 Feb 2016 17:20:42 -0800 Subject: iio: chemical: atlas-ph-sensor: switch regmap cache switch from using REGCACHE_FLAT to REGCACHE_RBTREE so initial hw values are read from device. This also allows some volatile ranges to be dropped. Note that REGCACHE_FLAT is intended only for very low lag cases so doesn't do nice things like read initial values from the device. Hence this change.
