Subject: [PATCH 00/18] GMA500 updates

This set of patches tackles three basic things

- Add support for Moorestown (not yet usable as it needs a memory allocator)
- Completely remove all the ttm related glue from the driver
- Turn on SDVO support on Poulsbo - which should get the various non panel
users working

Getting useful Moorestown support will need the power management tackling
further, memory allocator and possibly MIPI panel support. For now the priority
is Poulsbo.

Alan Cox (17):
gma500: turn on psb SDVO
gma500; kill off TTM
gma500: pull mrst firmware stuff into its own header
gma500: Clean up more unused structures and code
gma500: We don't support the CI either
gma500: delete the RAR handling
gma500: Add Moorestown identifiers
gma500: Moorestown does its setup differently
gma500: enable Moorestown CRTC handling
gma500: add framebuffer setup
gma500: Add Moorestown backlight support
gma500: Makefiles
gma500: Add moorestown specific data to the device structure
gma500: Add moorestown config structures
gma500: Make some of the lvds operations non-static
gma500: Add moorestown lvds driver code
gma500: begin adding Moorestown support

Justin P. Mattock (1):
drivers:staging:gma500 Remove extra semi-colon.

Subject: [PATCH 01/18] gma500: begin adding Moorestown support

The Moorestown systems have some graphics differences we care about and some
we don't need to.

To start with it has a single pipe and that pipe can be used for LVDS

- * non-locked-up status for a while to avoid an excessive
- * amount of lockup checks from every waiting thread.

I know you're not actually changing anything here, but opregion supports
requesting brightnesses between 0 and 255 - it'd be easier if we only
had one level of scaling, rather than having to map that to a percentage
only for it to be remapped to the hardware.

Is Moorestown known as GMA500 or GMA600? Is there some more generic name
that would cover all of them?

(Clearly not a high-priority issue, given the set of hardware supported
by the i915 driver)

GMA600 if I remember rightly

I'm not aware of a generic naming for them.
