From 3450de99d76555fce1cc22783108ea8603fefda5 Mon Sep 17 00:00:00 2001 From: Jon Medhurst Date: Thu, 26 Jul 2012 15:01:40 +0100 Subject: configs: vexpress: Enable TC2 cpufreq driver Note, for the sake of a faster boot and better performance, we default to maximum CPU clock frequency (CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE) and will rely on user-side scripts on Android and Ubuntu to change this as appropriate for big.LITTLE power saving. E.g. changing LITTLE cores to 'ondemand'.
