Thanks for the Acked-by.

However, this patch depends on this other series of mine that's merged
into your phy tree:

https://lore.kernel.org/linux-clk/176661322399.4169.14248756511703978007@lazor/

Stephen asked for an Acked-by for that series or an immutable branch.

This will allow us to remove round_rate from the clk core.

I also have a small series to post that's dependent on all of this that
lets us get rid of the noop determine_rate implementations that only
'return 0'. I haven't posted that because of the dependencies.
