That looks correct to me, so:

Reviewed-by: Andre Przywara <andre.przywara at arm.com>

But out of curiosity, what is this used for? In patch 5/5 I see it being
used, but without a clue for what? Shouldn't enabling an I2C node be
accompanied by some child node, presenting the device on the bus?
I guess this I2C is not on some kind of "header" on that laptop?

Cheers,
Andre.
