Drivers supporting multiple clusters or multiple 'struct cpufreq_policy' instances may need to keep some per-policy data. If the core doesn't support them, 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 completely for driver's internal use. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> --- include/linux/cpufreq.h | 3 +++ 1 file changed, 3 insertions(+)
