From 68a48afa6540f0bd193167f91283915ca8a4225e Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 10 Oct 2017 11:20:03 +0800 Subject: [PATCH] dt-bindings: display: sun4i: Add binding for A31 HDMI controller The HDMI controller in the A31 SoC is slightly different from the earlier version. In addition to the TMDS clock and DDC controls, this version now takes a second DDC clock input. Add a compatible string for it, and add the DDC clock input to the list of clocks required.
