[PATCH v4 2/7] regulator: axp20x: prepare support for multiple AXP chip families
From: Boris BREZILLON
Date: Tue Jun 17 2014 - 03:40:51 EST
Rework the AXP20X_ macros to support the several chip families, so that
each family can define it's own set of regulators, and regulator matches.
Pass a match table to the axp20x_regulator_parse_dt function instead of
statically using the axp20x match table.
