I have bad news, but there are also good (not for me :P).
Overclock to 1.5 GHz will be removed. I explain why. All by "PLL4", which can not be so easily overclock and I think it will up to 1.3 GHz. This overclock that we now have is not quite good. If the CPU is lightly loaded, overclock gives a lot, but if you have some heavy operations the effect is completely the opposite.
As our device has an unusual chip, all the methods I have to write myself from zero. To overclock I have to write method to strengthen the bandwidth of PLL4.
The same goes for Voltage Control, I have to write the whole method.
In conclusion, it will be possible, but you have to wait a little longer, so do not expect these features in V3. Sorry
If I do not find a solution in the kernel, I will remove the SWAP function.
