Hi, Thank you for the review and for the very detailed comments. I updated the patch series to fix the problems identified. To make sure a register is really cached a regcache_read() is performed on cacheable registers.
The patch was tested using a wm8731 device. Changes since v1 (https://lkml.org/lkml/2016/8/4/327) + Fix regmap_cached() to return if a register is really cached instead of cacheable. + Remove unnecesary regcache_read() in regmap_read_debugfs() Cristian Birsan (2): regmap: Add a function to check if a regmap register is cached regmap: debugfs: Add support for dumping write only device registers drivers/base/regmap/internal.h | 1 + drivers/base/regmap/regmap-debugfs.c | 16 +++++++++++++--- drivers/base/regmap/regmap.c | 23 +++++++++++++++++++++++ 3 files changed, 37 insertions(+), 3 deletions(-) -- 1.9.1
