[Intel-gfx] [PATCH 0/2] Enable VLV to work in BIOS-less system.

[Chon Ming Lee]

In non PC system, such as IVI, may not use BIOS, instead it uses boot 
loader with only minimal system initialization.  Most of the time, boot 
loader doesn't come with VBIOS, and depends on device driver to fully 
initialize the display controller and GPU.

For Valleyview, without VBIOS, i915 fails to work.  The patch add some 
missing init code, such as doing a DPIO CMNRESET and program the GMBUS 
frequency. 

Chon Ming Lee (2):
  drm/i915: Send a DPIO cmnreset during driver load or system resume.
  drm/i915: Program GMBUS Frequency based on the CDCLK
