From ab0ea257fc58d8742f73f50fba3797dfe001aa3c Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Thu, 10 Dec 2015 09:42:16 +0000 Subject: cpufreq: st: Provide runtime initialised driver for ST's platforms The bootloader is charged with the responsibility to provide platform specific Dynamic Voltage and Frequency Scaling (DVFS) information via Device Tree. This driver takes the supplied configuration and registers it with the new generic OPP framework, to then be used with CPUFreq.
