From 2449d33a40553504867f407dd713e9bcf6f9fe24 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Mon, 10 Mar 2014 15:43:18 +0530 Subject: cpufreq: SPEAr: Instantiate as platform_driver As multiplatform build is being adopted by more and more ARM platforms, initcall function should be used very carefully. For example, when SPEAr cpufreq driver is enabled on a kernel booted on a non-SPEAr board, we will get following boot time error: spear_cpufreq: Invalid cpufreq_tbl To eliminate this undesired the effect, the patch changes SPEAr driver to have it instantiated as a platform_driver. Then it will only run on platforms that create the platform_device "spear-cpufreq". This patch also creates platform node for SPEAr13xx boards.
