[PATCH 0/9] clk: pistachio: Assorted changes

[Ezequiel Garcia]

This patchset contains a bunch of clock changes for the Pistachio
clock driver.

The nine patches in this series are not really related, but I wasn't
sure it was worth to prepare a separate patchset for each group.
However, if this makes it harder to review, I can send different groups
of related patches.

Here's a brief summary of the patch groups:

Patches 1 and 2 clean up the PLL lock handling.

Patch 3 implements PLL rate adjustment, and in particular allows to support
small (i.e. neighbor-constrained) changes of the fractional PLL rate.

Patch 4 to 7 implements MIPS PLL rate change propagation and introduces
a table of MIPS PLL rate parameters.

Patch 8 adds some very useful sanity checks on integer and fractions PLL
set_rate(), to make sure the parameters are modified only when it's legal
to do so.

Patch 9 fixes the list of critical clocks.

None of these are urgent fixes so this is all v4.2 material.
