[PATCH 5/5] fbdev: tdfxfb: Program the initial video mode
From: Daniel Palmer <hidden>

framebuffer layer, the rest · Maintainers:
Helge Deller, Linus Torvalds
If the card does not get bound to by fbcon set_par() never happens and the initial video mode is not setup and the display detects no signal. Program the video mode and also clear the framebuffer memory so random garbage isn't displayed.
