Subject: [PATCH v1] drm/panel: simple: Tune timing for ET057090DHU
Date: Wed, 26 Jan 2022 17:55:06 +0100	[thread overview]
Message-ID: <20220126165506.222331-1-francesco.dolcini@toradex.com> (raw)

From: Oleksandr Suvorov <oleksandr.suvorov@toradex.com>

VESA Display Monitor Timing v1.13 has recommendations for the historical
VGA mode 640x480 60Hz. These parameters are compatible with EDT
ET057090DHU recommended timings.

Use VESA DMT timing parameters for EDT ET057090DHU panel.
