I will break out the gpio to separate

Yeah sure regs = <a>, <b>, <c> for a single node is OK if that's what
you mean.

Strange syntax in the last line there. GFC42'h uhm.

But that looks a bit mingled actually. However I think you will be
much happier if you split it into individual devices as I wanted to.
It will be easier to maintain and simpler code even if the device tree
may look a bit strange.
