From 3e692693dbc02420fd5bea45a51070121446ace6 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 9 May 2014 17:40:31 +0100 Subject: cpufreq: Enable big.LITTLE cpufreq driver on arm64 There are arm64 big.LITTLE systems so enable the big.LITTLE cpufreq driver. While IKS is not available for these systems the driver is still useful since it manages clusters with shared frequencies which is the common case for these systems. Long term combining the cpufreq-cpu0 and big.LITTLE drivers may be a more sensible option but that is substantially more complex especially in the case of IKS.
