[PATCH V4 2/3] cpufreq: add support for intermediate (stable) frequencies

2014-05-21 Thread Viresh Kumar
Douglas Anderson, recently pointed out an interesting problem due to which udelay() was expiring earlier than it should. While transitioning between frequencies few platforms may temporarily switch to a stable frequency, waiting for the main PLL to stabilize. For example: When we transition betwe
