From 71b03a96ffe24bd295fff3197ff7f5fc230ce2e2 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Thu, 21 Dec 2017 12:02:29 +0100 Subject: [PATCH] dt-bindings: display: sun4i-drm: Add LVDS properties Some clocks and resets supposed to drive the LVDS logic in the display engine have been overlooked when the driver was first introduced. Add those additional resources to the binding, and we'll deal with the ABI stability in the code.
