From f91b7c62e0cdb8a1a72b61b16fcd48858a7d9193 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 6 Jan 2015 10:35:11 +0800 Subject: [PATCH] ARM: sunxi: Register cpufreq-dt for sun[45678]i On sun[45678]i, we have one cluster of identical cores sharing a clock, which is ideal for using cpufreq-dt. Register a platform device for cpufreq-dt.
