The old binding said:

-Required properties of an internal channel when:
- - It is the only enabled channel of the bond (or)
- - If it acts as primary among enabled bonds

-- renesas,primary-bond: empty property indicating the channel
acts as primary
- among the bonded channels.

so renesas,primary-bond is required for the only enabled node for
single channels configurations anyway?
