Hopefully you and Yadwinder can take this on? You probably have better access to the right people to ask. I did dig up my 4210 manual which actually has one place where it shows two options for FIN of VPLL: 24MHz and 27MHz. They don't seem to share any PMSK values that are the same. It seems like the tables were generated by choosing a bunch of frequencies that people would probably like to make and then finding the best way to make that frequency (probably backed up by a bunch of simulation and testing of that exact combination). We have landed most of this series of patches (with a few modifications to later patches to avoid adding a global alias).. ...but if you decided to go a different way we'll take your version of course (either now with a revert / re-pick or when we rebase later). :) -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
