+From c3f89434c9d778572cf09e8327bd047b11d48b90 Mon Sep 17 00:00:00 2001
+From: Boris BREZILLON <boris.brezillon@free-electrons.com>
+Date: Fri, 10 Apr 2015 12:09:04 +0800
+Subject: [PATCH] regulator: axp20x: Add support for AXP22X regulators
+
+Add AXP22X regulator definitions and variant id associations.
+This introduces a new "switch" type output for one of the regulators.
+It is a switchable secondary output of one regulator, with the same
+voltage level as the primary output.
