From 6a0712f6f199e737aa5913d28ec4bd3a25de9660 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Tue, 9 Feb 2016 10:30:39 +0530 Subject: PM / OPP: Add dev_pm_opp_set_rate() This adds a routine, dev_pm_opp_set_rate(), responsible for configuring power-supply and clock source for an OPP. The OPP is found by matching against the target_freq passed to the routine. This shall replace similar code present in most of the OPP users and help simplify them a lot.
