4 Subject: [PATCH] regulator: axp20x: Add support for AXP22X regulators
5
6 Add AXP22X regulator definitions and variant id associations.
7 This introduces a new "switch" type output for one of the regulators.
8 It is a switchable secondary output of one regulator, with the same
9 voltage level as the primary output.
