gpu: host1x: Fix a few sparse warnings

2013-12-03T09:06:29Z

Include the bus.h header, so that various function declarations are visible in the source file that implements those functions. This keeps sparse from suggesting that they should be made static. Make the host1x_bus_type variable static since it isn't used globally. Finally replace the slightly unsafe dev_set_name(dev, name) by the more secure dev_set_name(dev, "%s", name).

gpu: host1x: Silence a few warnings with LPAE=y

2013-11-28T14:13:47Z

When building with LPAE=y (64-bit dma_addr_t), the following warnings are seen: drivers/gpu/host1x/hw/cdma_hw.c:57:3: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t' drivers/gpu/host1x/hw/debug_hw.c:167:10: warning: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'dma_addr_t' The agreed-to solution for this is upcast to u64 and using %llx.

gpu: host1x: Add syncpoint base support

2013-10-31T08:55:48Z

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 Reviewed-by: Terje Bergstrom Signed-off-by: Thierry Reding

gpu: host1x: Add 'flags' field to syncpt request

2013-10-31T08:55:47Z

Functions host1x_syncpt_request() and _host1x_syncpt_alloc() have been taking a separate boolean flag ('client_managed') for indicating if the syncpoint value should be tracked by the host1x driver. This patch converts the field into generic 'flags' field so that we can easily add more information while requesting a syncpoint. Clients are adapted to use the new interface accordingly.

gpu: host1x: Disable clock on probe failure

2013-10-31T08:55:46Z

Add a missing clk_disable_unprepare() before returning from the driver's .probe() function on error. Signed-off-by: Wei Yongjun Reviewed-by: Terje Bergstrom Signed-off-by: Thierry Reding

gpu: host1x: Add support for Tegra114

2013-10-31T08:55:41Z

Tegra114 uses a slightly updated version of host1x with an additional syncpoint. Signed-off-by: Thierry Reding

drm/tegra: Move driver to DRM tree

2013-10-31T08:55:40Z

In order to make subsystem-wide changes easier, move the Tegra DRM driver back into the DRM tree. Signed-off-by: Thierry Reding

gpu: host1x: Use relative include paths

2013-10-31T08:55:40Z

This is slightly safer than adding -Idrivers/gpu/host1x to cflags-y. Signed-off-by: Thierry Reding

drm/tegra: Move subdevice infrastructure to host1x

2013-10-31T08:55:33Z

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 functionality

2013-10-31T08:20:11Z

Expose the buffer objects, syncpoint and channel functionality in the public public header so that drivers can use them. Signed-off-by: Thierry Reding
