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.
