From 8a67f0ef2b684b34162d39e8f436fe39e9635a19 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Mon, 1 Apr 2013 12:57:49 +0000 Subject: cpufreq: ARM big LITTLE: Add generic cpufreq driver and its DT glue big LITTLE is ARM's new Architecture focussing power/performance needs of modern world. More information about big LITTLE can be found here: http://www.arm.com/products/processors/technologies/biglittleprocessing.php http://lwn.net/Articles/481055/ In order to keep cpufreq support for all big LITTLE platforms simple/generic, this patch tries to add a generic cpufreq driver layer for all big LITTLE platforms. The driver is divided into two parts: - Core driver: Generic and shared across all big LITTLE SoC's - Glue drivers: Per platform drivers providing ops to the core driver This patch adds in a generic glue driver which would extract information from Device Tree. Future SoC's can either reuse the DT glue or write their own depending on the need. Signed-off-by: Sudeep KarkadaNagesha Signed-off-by: Viresh Kumar Signed-off-by: Rafael J.
