2013-12-19gpu: host1x: Add MIPI pad calibration supportThierry Reding1-0/+2
This driver adds support to perform calibration of the MIPI pads for CSI and DSI. Signed-off-by: Thierry Reding <[email protected]>
2013-10-31gpu: host1x: Add syncpoint base supportArto Merilainen1-0/+2
This patch adds support for hardware syncpoint bases. This creates a simple mechanism to stall the command FIFO until an operation is completed. Signed-off-by: Arto Merilainen <[email protected]> Reviewed-by: Terje Bergstrom <[email protected]> Signed-off-by: Thierry Reding <[email protected]>
2013-10-31drm/tegra: Move subdevice infrastructure to host1xThierry Reding1-5/+4
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.

2013-09-03gpu: host1x: Sort drivers by probe orderThierry Reding1-1/+1
External driver declarations are sorted by probe order for consistency. Signed-off-by: Thierry Reding <[email protected]>
2013-06-22gpu: host1x: Rework CPU syncpoint incrementArto Merilainen1-4/+4
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.

2013-04-22gpu: host1x: Remove second host1x driverTerje Bergstrom1-0/+6
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.

2013-04-22gpu: host1x: Add host1x driverTerje Bergstrom1-0/+96
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.
