@Stephen, @Michael It has been over seven months since the first series submission for review. Moreover the reset-part has already got @Philipp's ab tag. Please merge it in. Short summary regarding this patchset. The series starts from fixing of the clocks glitching cause by the Renesas 5P49V6901 chip in some circumstances. Afterwards a few more modifications are introduced to finally finish the Baikal-T1 CCU unit support up and prepare the code before adding the Baikal-T1 PCIe/xGMAC support. First of all it turned out I specified wrong DW xGMAC PTP reference clock divider in my initial patches. It must be 8, not 10. Secondly I was wrong to add a joint xGMAC Ref and PTP clock instead of having them separately defined. The SoC manual describes these clocks as separate fixed clock wrappers. Finally in order to close the SoC clock/reset support up we need to add the DDR and PCIe interfaces reset controls support. It's done in two steps. First I've moved the reset-controls-related code into a dedicated module. Then the DDR/PCIe reset-control functionality is added. As the series finalization we've decided to convert the Baikal-T1 clock/reset source drivers to mainly being the platform device driver and pre-initialize the basic clocks only at the early kernel boot stages.
