From 790d849bf811a8ab5d4cd2cce0f6fda92f6aebf2 Mon Sep 17 00:00:00 2001 From: Jacob Tanenbaum Date: Thu, 19 Nov 2015 10:29:01 -0500 Subject: cpufreq: pcc-cpufreq: update default value of cpuinfo_transition_latency The cpufreq documentation specifies policy->cpuinfo.transition_latency the time it takes on this CPU to switch between two frequencies in nanoseconds (if appropriate, else specify CPUFREQ_ETERNAL) currently pcc-cpufreq does not expose the value and sets it to zero. I changed the pcc-cpufreq driver and it's documentation to conform to the default value specified in Documentation/cpu-freq/cpu-drivers.txt Signed-off-by: Jacob Tanenbaum Acked-by: Viresh Kumar Signed-off-by: Rafael J.
