gpu: host1x: Add syncpoint base support

2013-10-31T08:55:48+00:00

This patch adds support for hardware syncpoint bases. This creates
a simple mechanism to stall the command FIFO until an operation is
completed.

drm/tegra: Move subdevice infrastructure to host1x

2013-10-31T08:55:33+00:00

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: Rework CPU syncpoint increment

2013-06-22T10:43:55+00:00

This patch merges host1x_syncpt_cpu_incr to host1x_syncpt_incr() as
they are in practise doing the same thing. host1x_syncpt_incr() is
also modified to return error codes. User space interface is modified
accordingly to pass return values.

gpu: host1x: Remove second host1x driver

2013-04-22T10:39:59+00:00

Remove second host1x driver, and bind tegra-drm to the new host1x
driver. The logic to parse device tree and track clients is moved
to drm.c.

gpu: host1x: Add host1x driver

2013-04-22T10:32:40+00:00

Add host1x, the driver for host1x and its client unit 2D. The Tegra
host1x module is the DMA engine for register access to Tegra's
graphics- and multimedia-related modules. The modules served by
host1x are referred to as clients. host1x includes some other
functionality, such as synchronization.
