I prefer sg2000/sg2002 are different chips, or at least an enhanced version of existed cv1812/cv1813. It is not a simple rename. For this patch, the sg2000 doesn't need to disable A53 related clocks like cv18xx series. So this compatible is needed to bind to this new logic. Thanks, Inochi

I'm not disputing the unique compatible - you previously mentioned that Sophgo were considering rebranding the cvXXXX series of chips going forward and that one particular chip might undergo a name change. I was wondering if this was that chip or just another device in the series. Thanks, Conor.

For your question, this is the rename chip I mentioned. This is the name mapping I have known: cv1812cp -> sg2000 cv1813h -> sg2002

SG2000 series SoC has the same clock as CV1810 series, but the clock related to A53 is functional in SG2000 series. So a new compatible string is needed for the new SoC. Add definition for the clock controller of the SG2000 series SoC.
