/*
* Switching the CPU from the L2 or L3 frequencies (300 and 200 Mhz
* respectively) to L0 frequency (1.2 Ghz) requires a significant
* amount of time to let VDD stabilize to the appropriate
* voltage. This amount of time is large enough that it cannot be
* covered by the hardware countdown register. Due to this, the CPU
* might start operating at L0 before the voltage is stabilized,
* leading to CPU stalls.
*
* To work around this problem, we prevent switching directly from the
* L2/L3 frequencies to the L0 frequency, and instead switch to the L1
* frequency in-between. The sequence therefore becomes:
* 1. First switch from L2/L3(200/300MHz) to L1(600MHZ)
* 2. Sleep 20ms for stabling VDD voltage
* 3. Then switch from L1(600MHZ) to L0(1200Mhz).
