A few questions came up whilst converting this one.
1) What is actually required?
- Checking Linux driver, interrupt is not, and the tx-supply could
be supplied by a stub regulator as long as it's always on.
As such I have reduced the required list to just compatible and reg.
2) What is the regulator called?
- It's tx-supply in the binding doc, but the driver requests tx_sup.
I'll post a fix patch to change the driver to fix this as it makes
little sense.
Andrew's email is bouncing so until someone else steps up I have
listed myself as maintainer for this binding.
