[PATCH] drm/meson: Add support for DMT modes on HDMI
From: Neil Armstrong
Date: Thu Mar 08 2018 - 14:56:16 EST
This patch adds support for DMT display modes over HDMI.
The modes timings configurations are from the Amlogic Vendor linux tree
and tested over multiples monitors.
Previously only a selected number of CEA modes were supported.
Only these following modes are supported with these changes:
- 640x480@60Hz
- 800x600@60Hz
- 1024x768@60Hz
- 1152x864@75Hz
- 1280x1024@60Hz
- 1600x1200@60Hz
- 1920x1080@60Hz
The associated code to handle the clock rates is also added.
