The Allwinner A31 MIPI D-PHY block supports both tx and rx directions, although each instance of the block is meant to be used in one direction only. There will typically be one instance for MIPI DSI and one for MIPI CSI-2 (it seems unlikely to ever see a shared instance). Describe the direction with a new allwinner,direction property. For backwards compatibility, the property is optional and tx mode should be assumed by default.
