From 9a8187c00373bce839388574910f72711c9c4c33 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 17 Oct 2017 20:18:01 +0800 Subject: drm/sun4i: Add support for A10 display pipeline components The A10 display pipeline has 2 frontends, 2 backends, and 2 TCONs. This patch adds support (or a compatible string in the frontend's case) for these components. The TCONs support directly outputting to CPU/RGB/LVDS LCD panels, or it can output to HDMI via an on-chip HDMI controller, or CVBS/YPbPr/VGA signals via on-chip TV encoders. These additional encoders are not covered in this patch.
