f8aed700c6 drm/i915: Set crtc/clone mask in different output devices
Based on Bspec each encoder has different sharing pipe property,
i.e. Integrated or SDVO TV both will occupy one pipe exclusively,
and sdvo-non-tv and crt are allowed to share one. The patch moves
sharing judgment into differnet output functions, and sets the right
clone bit.

This fixes both HDMI outputs choosing the same pipe.

32f9d658ae drm/i915: Add eDP support on IGDNG mobile chip
This adds embedded DisplayPort support on next mobile chip which
aims to replace origin LVDS port. VBT's driver feature block has
been used to determine the type of current internal panel for eDP
or LVDS.

Currently no panel fitting support for eDP and backlight control
would be added in future.

eebc863e46 drm/i915: Fix channel ending action for DP aux transaction
We should use current channel 'status' bits to clear DP aux channel's
done and error bits, instead of using the channel setting bits, that
will set send/busy bit again to initiate new transaction.

This also includes also some minor cleanup.

1ae8c0a56e drm/i915: Make driver less chatty
Convert many printk calls to DRM_DEBUG calls to reduce kernel log noise
for normal activities. Switch other printk calls to DRM_ERROR or DRM_INFO.

fb0f8fbf97 drm/i915: Generate 2MHz clock for display port aux channel I/O. Retry I/O.
The display port aux channel clock is taken from the hrawclk value, which is
provided to the chip as the FSB frequency (as far as I can determine). The
strapping values for that are available in the CLKCFG register, now used to
select an appropriate divider to generate a 2MHz clock.

In addition, the DisplayPort spec requires that each aux channel I/O be
retried 'at least 3 times' in case the sink is idle when the first request
comes in.
