drm: Only select I2C_ALGOBIT for drivers that actually need it
While working on a drm driver that doesn't need the i2c algobit stuff I
noticed that DRM selects this code even though only 8 drivers actually use
it. While also only some drivers use i2c, keep the select for I2C for the
next cleanup patch. Still prepare this already by also selecting I2C for
the individual drivers.

fe7aebb40d ACPI: video: Add Nvidia WMI EC brightness control detection (v3)
On some new laptop designs a new Nvidia specific WMI interface is present
which gives info about panel brightness control and may allow controlling
the brightness through this interface when the embedded controller is used
for brightness control.

When this WMI interface is present and indicates that the EC is used,
then this interface should be used for brightness control.

Changes in v2:
- Use the new shared nvidia-wmi-ec-backlight.h header for the
  WMI firmware API definitions
- ACPI_VIDEO can now be enabled on non X86 too,
  adjust the Kconfig changes to match this.

Changes in v3:
- Use WMI_BRIGHTNESS_GUID define

e40f97ef12 drm/gma500: Drop DRM_GMA600 config option
With support for the MID-only Medfield chips removed, simply build
the complete driver if DRM_GMA500 has been selected. Anyone who wants
to enable one of the chips would probably also want the rest.

92b6f89f6b drm: Add separate Kconfig option for fbdev helpers
For drivers which might want to disable fbdev legacy support.

Select the new option in all drivers for now, so this shouldn't result
in any change. Drivers need some work anyway to make fbdev support
optional (if they have it implemented, that is), so the recommended
way to expose this is by adding per-driver options. At least as long
as most drivers don't support disabling the fbdev support.

v2: Update for new drm drivers msm and rcar-du. Note that Rob's msm
driver can already take advantage of this, which allows us to build
msm without any fbdev depencies in the kernel!

v3: Move the MODULE_* stuff from the fbdev helper file to
drm_crtc_helper.c.

0c1a14c2c1 gma500:fix build failure for 3.9-rc5
Last version of this patch is not clear enough and X86 duplicated.

This patch fixes build failure of v3.9-rc5 and rc6.
When config ACPI_VIDEO as m, DRM_GMA500 as y, here comes the failure.
GMA5/600 needs acpi_video just like nouveau.
And some tab type fix by the way.

Failure message:
drivers/built-in.o: In function `psb_driver_load':
kernel-3.9-rc5/drivers/gpu/drm/gma500/psb_drv.c:340: \

3abcf41fb1 gma500: Move the basic driver out of staging
This driver supports unaccelerated KMS display, and accelerated console
handling on the Intel Poulsbo, Oaktrail, Cedarview and Medfield hardware.

For the initial merge Medfield will be left out as it needs considerable
further work to reach a decent standard

Begin by adding the Makefiles and Kconfig. These are not yet plumbed into
the DRM layer so will have no effect on their own
