From 01fb4d3c39d35b725441e8a9a26b3f3ad67793ed Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Wed, 9 Dec 2015 08:01:47 +0530 Subject: PM / OPP: Parse 'opp--' bindings OPP bindings (for few properties) allow a platform to choose a value/range among a set of available options. The options are present as opp--, where the platform needs to supply the string. The OPP properties which allow such an option are: opp-microvolt and opp-microamp. Add support to the OPP-core to parse these bindings, by introducing dev_pm_opp_{set|put}_prop_name() APIs. Signed-off-by: Viresh Kumar Tested-by: Lee Jones Signed-off-by: Rafael J.
