From 1e63bd9cc43db5400a1423a7ec8266b4e7c54bd0 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Sun, 15 Dec 2013 03:24:45 -0800 Subject: [PATCH] Input: pmic8xxx-pwrkey - migrate to regmap APIs Use the regmap APIs for this driver instead of custom pm8xxx APIs. This breaks this driver's dependency on the pm8xxx APIs and allows us to easily port it to other bus protocols in the future.
