Alexandre Courbot 8ba9ff1163 drm/nouveau: support for probing platform devices
Add a platform driver for Nouveau devices declared using the device tree
or platform data. This driver currently supports GK20A on Tegra
platforms and is only compiled for these platforms if Nouveau is
enabled.

Nouveau will probe the chip type itself using the BOOT0 register, so all
this driver really needs to do is to make sure the module is powered and
its clocks active before calling nouveau_drm_platform_probe().

Heavily based on work done by Thierry Reding.

Jean Delvare a386c006a7 ACPI / gpu / drm: Stop selecting VIDEO_OUTPUT_CONTROL
ACPI_VIDEO no longer depends on VIDEO_OUTPUT_CONTROL, so drivers which
want to select ACPI_VIDEO no longer have to select
VIDEO_OUTPUT_CONTROL.

Daniel Vetter 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.

Maarten Lankhorst 1107276c8a drm/nouveau: always select ACPI_VIDEO if ACPI is enabled.
Having nouveau builtin would still allow ACPI_VIDEO to be used as external module
if some of the deps for acpi_video have not been met, which would result in a linking
failure. Solve this by selecting all dependencies as well.

Dave Airlie 1f3a574a4b Merge branch 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next
Nothing terribly exciting in here probably:
- reworked thermal stuff from mupuf/I, has a chance of possibly working
well enough when we get to being able to reclock..
- driver will report mmio access faults on chipsets where it's supported
- will now sleep waiting on fences on nv84+ rather than polling
- some cleanup of the internal fencing, looking towards sli/dmabuf sync
- initial support for anx9805 dp/tmds encoder
- nv50+ display fixes related to the above, and also might fix a few
other issues
- nicer error reporting (will log process names with channel errors)
- various other random fixes

If I build nouveau on ia64, Kconfig warns:

warning: (DRM_NOUVEAU) selects ACPI_WMI which has unmet direct dependencies (X86 && X86_PLATFORM_DEVICES && ACPI)
warning: (DRM_NOUVEAU) selects MXM_WMI which has unmet direct dependencies (X86 && X86_PLATFORM_DEVICES && ACPI_WMI)

Make all the ACPI support depend on X86 and select
X86_PLATFORM_DEVICES.

David Rientjes 6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

CONFIG_ACPI_VIDEO depends on more than just CONFIG_ACPI, so add those
dependencies to the Kconfig select condition.  The case where some
dependencies fail to be satisfied should be handled correctly, because
in that case the ACPI_VIDEO symbols we use are converted into
static-inline stubs.

    drm/nouveau: support fetching LVDS EDID from ACPI

    Based on a patch from Matthew Garrett.

    Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
    Acked-by: Matthew Garrett <mjg@redhat.com>

It doesn't seem to revert cleanly, but the problem lies in these
two config entries:

CONFIG_ACPI=y
CONFIG_ACPI_VIDEO=m

Adding a select for ACPI_VIDEO appears to be the best solution, and
is comparable to what is done in DRM_I915.  Builds, boots, and appears to
work correctly.

Ben Skeggs 6ee738610f drm/nouveau: Add DRM driver for NVIDIA GPUs
This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.

This driver is a KMS-based driver and requires a compatible nouveau
userspace libdrm and nouveau X.org driver.

This driver requires firmware files not available in this kernel tree,
interested parties can find them via the nouveau project git archive.

This driver is reverse engineered, and is in no way supported by nVidia.

Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
is available, and the kms driver should support driving nearly all
output types (displayport is under development still) along with supporting
suspend/resume.

This work is all from the upstream nouveau project found at
nouveau.freedesktop.org.
