File:0001-Introduce-dynamic-frequency-scaling.patch

This patch enables frequency scaling independent of voltage. It defines a new config (CONFIG_DFS) which must be enabled to employ the feature, along with CONFIG_DFS_MAX_VOLTAGE which must be set to the fixed MPU voltage (in microvolts) being used in the system. This patch is intended for use on AM33xx processors, and is useful in systems which employ a fixed voltage regulator, or other systems in which dynamic voltage changing is not possible (such as AM33xx's ZCE package). Frequency scaling is still performed via the usual cpufreq interface. OPP's which exceed CONFIG_DFS_MAX_VOLTAGE will be automatically disabled.
