This patchset is based on 4.1-rc1 but it had been tested on 4.2-rc1.
I'll send a new patch which based on 4.2-rc1.

This patchset contains some general PLL fixes and MMPLL set rate
support. We can say the last one is also a fix because changing some
specific rate on MMPLL may fail in current implementation.
