linux-toradex.git/drivers/gpu/host1x, branch v3.15-rc1

Merge tag 'drm/tegra/for-3.15-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next

drm/tegra: Changes for v3.15-rc1

Implement eDP support for Tegra124 and support the PRIME vmap()/vunmap()
operations.

A symbol that is required for upcoming V4L2 support is now exported by
the host1x driver.

Relicense drivers under the GPL v2 for consistency. One exception is the
public header file, which is relicensed under MIT to abide by the common
rule.

Tegra V4L2 camera driver needs this function to do frame capture.

gpu: host1x: do not check previously handled gathers

2014-02-12T06:50:37+00:00

When patching gathers, we don't need to check against
gathers with lower indices than the current one, as
they are guaranteed to already have been handled.

gpu: host1x: Remove unnecessary include

2014-01-14T13:39:45+00:00

Nothing from the asm/mach/irq.h header is needed in this file, so there
is no need to include it.

gpu: host1x: Add Tegra124 support

2013-12-19T08:29:52+00:00

Tegra124 has 192 syncpoints whereas its predecessors had 32 syncpoints.
This required changes to the hardware register layout.

gpu: host1x: Fix build warnings

2013-12-19T08:29:52+00:00

When debugfs support isn't enabled, gcc complains about some variables
being unused. To avoid further #ifdefery, move debugfs specific setup
code into static functions and use IS_ENABLED(CONFIG_DEBUG_FS) to have
the compiler, rather than the preprocessor, discard them when unused.
The advantage of doing it this way is that all the code will be
compile-tested whether or not debugfs support is enabled.

gpu: host1x: Increase compile test coverage

2013-12-19T08:29:51+00:00

The ARCH_MULTIPLATFORM dependency was introduced back when Tegra didn't
support multiplatform yet as a means to allow the driver to be easily
compile-tested along with other DRM drivers. In the meantime, the new
COMPILE_TEST Kconfig option has been introduced for exactly that
purpose, so use that instead to clarify the intention.

gpu: host1x: Fix more sparse warnings

2013-12-19T08:29:51+00:00

Include the linux/host1x.h and dev.h headers so that function prototypes
are visible to keep sparse from suggesting that their implementations be
made static.

gpu: host1x: Use the correct HW headers for host1x02

2013-12-19T08:29:51+00:00

An earlier patch added a subset of the required HW specific header files
but didn't actually include the right ones when compiling for host1x02.

gpu: host1x: Export public API

2013-12-19T08:29:50+00:00

Make the public API symbols visible so that depending drivers can be
built as a module.
