[PATCH v1 35/35] drm/modes: Introduce more named modes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now that we can easily extend the named modes list, let's add a few more
analog TV modes that were used in the wild, and some unit tests to make
sure it works as intended.
