"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 problem with this series is it breaks an old kernel with new dt. You can partially mitigate that with stable kernel backport, but IMO keeping the old name is not a burden to maintain.
As suggested I only removed vpll from the binding document, but not from the code. The code still handles the old binding as well.
