From c20f80d0b89cf43be964797e6170f085b312ea01 Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Fri, 15 Apr 2022 17:21:31 +0200 Subject: dt-bindings: sun6i-a31-mipi-dphy: Add optional direction property 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.
