Default DRM driver for OMAP 3

Please pull to include the new DRM driver for OMAP 3. This driver
supports the framebuffer driver, exports hooks for the PVR driver and
also probe and parse the monitor EDID, trying to set the best
resolution available.

With this driver I'm able to get resolutions up to 1400x900@60-32bit,
as it can't go higher because of the pixel clock limitation.

The following patches touches mostly just omap related files, and the
ones that are more generic are also only related with platform
devices.

This looks like a maintenance nightmare. Its great that you guys have
the display issues worked out, but its bad that none of this is
upstream. There is no way I'm gonna accept this on the eve of the kernel
freeze.

True, not all is upstream yet, as we kind of just finished the driver.

These are the status of the patches:

Upstream already:
Sumit Semwal (1):
OMAP2, 3: DSS2: Create new file display.c for central dss driver
registration.

Not yet upstream, but included and used at the ti-omap4 branch for
Maverick and Natty:
Jeff McGee (1):
drm: Call platform register/unregister for platform drivers.

Also used at the ti-omap4 branch:
Sebastien Jan (1):
OMAP4: DSS: add generic notifier mechanism

New patches, but will also be applied and used at the ti-omap4 branch:
Ricardo Salveti de Araujo (5):
drm/omap: add common scaled modes
OMAP2: DSS2: Adding i2c_bus_num to panel_generic_dpi_data to
probe the eeprom
OMAP: DSS2: add get_edid and is_detected support
drm/omap: adding MODULE_ALIAS
UBUNTU: [Config] enable CONFIG_DRM_OMAP=m and
CONFIG_OMAP2_DSS_USE_DSI_PLL=y for omap

Rob Clark (10):
OMAP: DSS2: Expose API to get edid
OMAP: DSS2: Add default get/check timings functions
OMAP: DSS2: Add is_detected() driver API
OMAP: DSS2: Add hotplug notify events
OMAP: DSS2: Add missing color formats
drm: psuedocolor support for ARGB modes
drm: platform multi-device support
fbops support for framebuffers with alpha channel
Adding omap_gpu drm display driver
omap2+: fix number of omap_vout resources

The good thing is that the generic changes are quite simple and most
contained for OMAP. The DRM driver itself is quite simple, basically
linking the DSS2 subsystem with DRM, and using the DRM functions to
implement the framebuffer driver.

As the user can still fix the resolution by setting it up at the
kernel command line (as we're currently using at the images), there's
no bad side effect of having and using this new driver besides getting
a new functionality.

I understand if we can't include this for natty, but don't really
think it's going to be a maintenance nightmare.

Thanks,

The fact that most of these patches are simple or are in use on the
ti-omap4 branch isn't relevant. The points that are important to the
distro kernel are a) this is a new feature and we are past feature
freeze, b) all but one of these patches diddle in existing source in
such a way so as to guarantee conflicts with future stable updates.


I'm quite open to experimentation in the ti-omap4 branch, but not in the
main distro kernel.
