From 7de36b0aa51a5a59e28fb2da768fa3ab07de0674 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Wed, 9 Dec 2015 08:01:46 +0530 Subject: PM / OPP: Parse 'opp-supported-hw' binding OPP bindings allow a platform to enable OPPs based on the version of the hardware they are used for. Add support to the OPP-core to parse these bindings, by introducing dev_pm_opp_{set|put}_supported_hw() APIs. Signed-off-by: Viresh Kumar Tested-by: Lee Jones Signed-off-by: Rafael J.
