From d23473828c1188805c9e0b2a2e5be158d07ce7de Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Fri, 5 Apr 2013 12:00:38 +0200 Subject: ARM: shmobile: sh73a0: add CPUFreq support This patch enables the use of the generic cpufreq-cpu0 driver on sh73a0. Providing a regulator, a list of OPPs in DT, combined with a virtual cpufreq-cpu0 platform device and a clock, attached to it is everything, the cpufreq-cpu0 driver needs. The first sh73a0 platform, implementing such CPUFreq support is kzm9g-reference.
