Jesse Barnes babea61dfb drm/i915: copy fetched mode state into crtc at setup_hw time v5
We already fetch and track other state into the main CRTC and encoder
structs, and for fastboot we need to do the same with the mode and clock
data we read out.

v2: fix debug print
v3: use fastboot param around state copy
v4: set clock and flags for crtc here instead of in setup_hw_state
v5: rename function to intel_crtc_mode_from_pipe_config for consistency (Chris)

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).

The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:

    1. The DRM provides synchronized access to the graphics hardware via
       the use of an optimized two-tiered lock.

    2. The DRM enforces the DRI security policy for access to the graphics
       hardware by only allowing authenticated X11 clients access to
       restricted regions of memory.

    3. The DRM provides a generic DMA engine, complete with multiple
       queues and the ability to detect the need for an OpenGL context
       switch.

    4. The DRM is extensible via the use of small device-specific modules
       that rely extensively on the API exported by the DRM module.


Documentation on the DRI is available from:
