[PATCH 02/16] drm/udl: Test pixel limit in mode-config's mode-valid function

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

 



The sku_pixel_limit is a per-device property, similar to the amount
of available video memory. Move the respective mode-valid test from
the connector to the mode-config structure.
