From d8d79f8f60c4363a0fa490ff1626be4bd5e003a3 Mon Sep 17 00:00:00 2001 From: Michal Suchanek Date: Sat, 11 Jul 2015 14:59:56 +0200 Subject: [PATCH] mfd: axp20x: Add axp152 support The axp152 is a stripped down version of the axp202 pmic with the battery charging function removed as it is intended for top-set boxes.
