Subject: [PATCH] regmap: Move documentation to regmap.h
Init functions defined in regmap*.c files are now prefixed with
__, take lockdep key and class parameters, and should not be
called directly: move the documentation to regmap.h, where the
macros are defined.
Signed-off-by: Nicolas Boichat <drinkcat@...omium.org>

Applies on top of this series:
[PATCHv2 0/3] regmap: Use different lockdep class for each regmap init call
sent earlier today.
