31a0685a42 gma500: Clean up some of the noise
We have a lot of debug type stuff we don't actually need any more.

8512e07487 gma500: introduce some register maps
All the conditional ugly register selection really wants to be
cleaned up. Use a struct describing each pipe and its registers.

This will also let us hide some of the oddments between platforms
for any future merging of bits together. In particular the way the
DPLL and FP registers randomly wander around.

d839ede47a gma500: opregion and ACPI
Add the opregion support and bring us in line with the opregion functionality in the
reference driver code. We can't share this with i915 currently because there are
hardcoded assumptions about dev_priv etc in both versions.

[airlied: include opregion.h fix]

9aba9d3a2c gma500: implement backlight functionality for Cedartrail devices
Basically a straight cut/paste from the reference driver code then
cleaned up a spot.

d235e64a43 cdv: continue synching up with updated reference code
In particular clean up the errata handling and correct the crtc masks. We do
this a bit differently using our device abstraction for neatness.

This doesn't address the ACPI opregion and hotplug plumbing, nor the IRQ related
changes that will need. It touches on backlight init but the full backlight
support is not in this change set.

055bf38d3d drm, gma500: Fix Cedarview boot failures in 3.3-rc
Production GMA3600/3650 hardware turns out to be subtly different to the
development platforms.  This combined with a minor driver bug is causing
the kernel to hang on these platforms.

This patch does the following

 - turn down a couple of messages that were meant to be debug and are
   causing much confusion

 - ensure the hotplug interrupt is disabled on Cedartrail systems.

 - fix a bug where gtt roll mode called psbfb_sync, which tries to sync
   the 2D engine. On other devices it is harmless as the 2D engine is
   present but not in use when in gtt roll mode, on Cedartrail it causes
   a hang

Without these changes 3.3-rc hangs on boot on Cedartrail based systems.

6a227d5fd6 gma500: Add support for Cedarview
Again this is similar but has some differences so we have a set of plug in
support. This does make the driver bigger than is needed in some respects
but the tradeoff for maintainability is huge.
