[v2,0/9] ARM: mstar: cpupll

Message

This series adds a basic driver for the PLL that generates
the cpu clock on MStar/SigmaStar ARMv7 SoCs.

Unfortunately there isn't much documentation for this thing
so there are few magic values and guesses.

This needs to come after the MPLL DT changes.

Changes since v2:
- Re-worked the series and ensure that 'make dt_binding_check' passes.
  The required commit is merged now, so it is okay.
- Fixed coding style issues in the driver and makes check_patch.pl happy
- Added one more commit for extending the opp_table for infinity2m.
