From 413fffc3a1db7f270afdf1ecb35c1edc013acc68 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Thu, 28 Aug 2014 11:22:23 +0530 Subject: cpufreq: Add support for per-policy driver data Drivers supporting multiple clusters or multiple 'struct cpufreq_policy' instances may need to keep per-policy data. If the core doesn't provide support for that, they might do it in the most unoptimized way: 'per-cpu' data. This patch adds another field in struct cpufreq_policy: 'driver_data'. It isn't accessed by core and is for driver's internal use only. Tested-by: Stephen Boyd Signed-off-by: Viresh Kumar Signed-off-by: Rafael J.
