From 67f50c75891681227896a61a8e4f66ff7c975840 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Thu, 27 Apr 2017 15:20:37 +0100 Subject: cpufreq: scpi: use new scpi_ops functions to remove duplicate code scpi_ops now provide APIs to get the transition_latency and to add OPPs to the devices making those logic redundant here. This patch makes use of those APIs and removes the redundant code in this driver. Cc: "Rafael J.
