From 59c699fe982aa0df961465654c4d87d109b127e6 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 24 Mar 2016 17:23:48 -0700 Subject: [PATCH] drm/panel: simple: Add the 7" DPI panel from Adafruit This is a basic TFT panel with a 40-pin FPC connector on it. The specification doesn't define timings, but the Adafruit instructions were setting up 800x480 CVT. v2: Add .bus_format and vsync/hsync flags.
