This is a continuous effort of Richard's work [1]. But that generic cpufreq driver has been rewritten with taking omap-cpufreq.c as the reference to adopt OPP library. Same as Richard's patch, the driver has no intention to support the multi-core systems that frequency and voltage can be scaled independently on different CPUs. Instead, it aims at uniprocessor (UP) and those symmetric multiprocessor (SMP) systems which share clock and voltage across all CPUs. I have seen patch from Mike changing omap-cpufreq driver to scale regulator from clk notifier. We can definitely make the same move for cpufreq-cpu0 later when the patch gets accepted.
