[PATCH] drm/msm/dp: Initialize the INTF_CONFIG register

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

 



Some bootloaders set the widebus enable bit in the INTF_CONFIG register,
but configuration of widebus isn't yet supported ensure that the
register has a known value, with widebus disabled.
