In order to make subsystem-wide changes easier, move the Tegra DRM
driver back into the DRM tree.

drm/tegra: Move subdevice infrastructure to host1x2013-10-31T08:55:33ZThierry Redingtreding@nvidia.com2013-10-14T12:43:22Zurn:sha1:776dc38403676f499a73d32e2e7c61eb5b42f736
The Tegra DRM driver currently uses some infrastructure to defer the DRM
core initialization until all required devices have registered. The same
infrastructure can potentially be used by any other driver that requires
more than a single sub-device of the host1x module.
Make the infrastructure more generic and keep only the DRM specific code
in the DRM part of the driver. Eventually this will make it easy to move
the DRM driver part back to the DRM subsystem.

gpu: host1x: Expose syncpt and channel functionality2013-10-31T08:20:11ZThierry Redingtreding@nvidia.com2013-09-24T14:30:32Zurn:sha1:35d747a81d7eb824bd0c3476cd0c564b52ad5353
Expose the buffer objects, syncpoint and channel functionality in the
public public header so that drivers can use them.

drm/tegra: Introduce tegra_drm_client structure2013-10-31T08:20:10ZThierry Redingtreding@nvidia.com2013-09-24T13:35:40Zurn:sha1:53fa7f7204c97dc0c86b99ff8365ad6a7b2ebd78
This structure derives from host1x_client. DRM-specific fields are moved
from host1x_client to this structure, so that host1x_client can remain
agnostic of DRM.

In preparation to support host1x clients other than DRM, move this
header into a public location.

Rename the host1x_to_drm_bo() macro to host1x_to_tegra_bo() for
consistency and fixup various stylistic issues.

drm/tegra: Rename gr2d to tegra-gr2d2013-10-31T08:20:09ZThierry Redingtreding@nvidia.com2013-10-14T12:44:54Zurn:sha1:a137ce3438cb1f75fc048e751921a4eaceee0123
Other drivers use the tegra- prefix in their names, so add it to this
driver's name as well for consistency.

drm/tegra: gr2d: Miscellaneous cleanups2013-10-31T08:20:09ZThierry Redingtreding@nvidia.com2013-09-26T14:09:43Zurn:sha1:c1bef81fe75bb0d6df9ee21f70eb39c0d854a8cc
Rework the address table code for the host1x firewall. The previous
implementation allocated a bitfield but didn't check for a valid pointer
so it could potentially crash. Instead, embed a static bitmap within the
gr2d structure to avoid the allocation and use the Linux bitmap API to
reduce code complexity.
Don't annotate the driver's .remove() function __exit. Even if built in
the driver can be unloaded via sysfs, so .remove() needs to stick around
after initialization. Also remove the explicit initialization of the
driver's .owner field to THIS_MODULE because that's now handled by the
driver core.
Furthermore make an error message more consistent with other subdrivers,
index the syncpts array for better readability, remove a gratuituous
newline and reorder some variable declarations to make the code easier
to read.

drm/tegra: Rename host1x_drm_context to tegra_drm_context2013-10-31T08:20:06ZThierry Redingtreding@nvidia.com2013-09-26T14:08:22Zurn:sha1:c88c363072c6dcd5427077f799b2711a10f616e4
The structure represents a context associated with a particular process
that has opened the Tegra DRM device and requested a channel. This is a
very DRM-specific notion and has nothing to do with host1x. Rename the
structure to more clearly mark the boundaries between the two.
