[PATCH 1/6 v3] mfd: tps65910: Commonize regmap access through header

From: Rhyland Klein
Date: Tue May 08 2012 - 11:44:46 EST

This change removes the read/write callback functions in favor of common
regmap accessors inside the header file. This change also makes use of
regmap_read/write for single register access which maps better onto what this
driver actually needs.

Signed-off-by: Rhyland Klein <rklein@xxxxxxxxxx>
---
v3: No change from v2 (other than rebased)
v2: implemented switching tps65910 drivers over to more directly accessing
the regmap rather than going through utility functions.
