"vpll" is a misnomer. A clock input to a device should be named after the usage in the device, not after the clock that drives it. On the rk3568 the same clock is driven by the HPLL. To fix that, this patch renames the vpll clock to ref clock. The clock name "vpll" is left for compatibility to old device trees.Can't we just say that the binding only takes the "ref" name, but the code still allows "vpll". I think I remember Rob suggesting something similar in the past. I don't think that we need to keep the binding(-validation) compatible with old devicetrees, but the kernel itself should stay compatible.
Sounds reasonable. I'll also add a patch changing the in-tree users next round.
