From 7302f0d6f939247c1c658b79aba0866c92560ff7 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Thu, 3 Dec 2020 14:25:40 +0100 Subject: [PATCH] drm/vc4: dsi: Add support for DSI0 Commit 4b265fe11fad4234b12d92dd8091f9aa0c878eea upstream. DSI0 was partially supported, but didn't register with the main driver, and the code was inconsistent as to whether it checked port == 0 or port == 1. Add compatible string and other support to make it consistent.
