From d0ec0a3e48d6fc56e5293be6b946cd60b099ea9c Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Fri, 25 Jan 2019 11:23:09 +0800 Subject: drm/sun4i: Add support for A23 display pipeline The A23's display pipeline is similar to the A33. Differences include: - Display backend supports larger layers, 8192x8192 instead of 2048x2048 - TCON has DMA input - There is no SAT module packed in the display backend Add support for the display pipeline and its components. As the MIPI DSI output device is not officially documented, and there are no A23 reference devices to test it, it is not covered by this patch.
