[PATCH 09/10] drm/mgag200: Store vidrst flag in device info

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

 



Set new vidrst flag in device info for models that synchronize with
external sources (i.e., BMCs). In modesetting, set the corresponding
bits from the device-info flag.
