We could combine the two bindings, but as the drivers are separate and it would be a little fiddly due to different buses let's keep the separating. To repeat questions from the ti,afe4403 binding. 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 request tx_sup I've left this alone for now. Andrew could you confirm what is intended for this? Signed-off-by: Jonathan Cameron Cc: Andrew F.
