[PATCH 1/2] drm/panel: Add Starry KR070PE2T

Pascal Roeleven dev at pascalroeleven.nl
Tue Mar 10 10:27:23 UTC 2020


The KR070PE2T is a 7" panel with a resolution of 800x480.

KR070PE2T is the marking present on the ribbon cable. As this panel is
probably available under different brands, this marking will catch
most devices.
