v3 -> v4

	- rebase v2 patch
	- use generic node name

Hi Mark, Rob

I posted ak4613 3 times (= v1 - v3), and v2 patch got Reviewed-by from Rob
(= https://lore.kernel.org/r/20200715220920.GA903738@bogus).
But in the same time, it got review from Fabio to use generic node name.
Then, I used v1 for v3 somehow and everything becoming wrong.
This patch should be OK. I added Rob's Reviewed-by on this patch, too.
