From 82a40b54820601aad0facf72050c62ae7fc7d4df Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Fri, 26 Sep 2014 15:41:02 +0200 Subject: [PATCH] ARM: imx53: clk: add ARM clock The ARM clock is a virtual clock feeding the ARM partition of the SoC. It controls multiple other clocks to ensure the right sequencing when cpufreq changes the CPU clock rate.
