[PATCH 09/13] OMAP: Disable smartreflex across DVFS

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch disables smartreflex for a particular voltage
domain when the the voltage domain and the devices belonging
to it is being scaled and re-enables it back once the scaling
is done.
