Imre Deak 319be8ae8a drm/i915: add port power domains
Parts that poke port specific HW blocks like the encoder HW state
readout or connector hotplug detect code need a way to check whether
required power domains are on or enable/disable these. For this purpose
add a set of power domains that refer to the port HW blocks. Get the
proper port power domains during modeset.

For now when requesting the power domain for a DDI port get it for a 4
lane configuration. This can be optimized later to request only the 2
lane power domain, when proper support is added on the VLV PHY side for
this. Atm, the PHY setup code assumes a 4 lane config in all cases.

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:
    http://dri.freedesktop.org/wiki/Documentation
    http://sourceforge.net/project/showfiles.php?group_id=387
