[PATCHv1 07/14] drm/omap: add support for physical size hints from display drivers

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

 



While physical size information is automatically parsed for EDID
based displays, we need to provide it manually for displays providing
one fixed mode.
