I skipped them, as I didn't have comments for them.

Are you sure about the third clock? Neither sm8150 nor sm8250 used the
qref clock. Or is that an omission on our side?

Hi Dmitry,

For SC7280 we need all the three clocks for this target. Same is being
used in downstream code as well. Hence I would need to update the
binding as well.
