2012-12-30Revert "drm: tegra: protect DC register access with mutex"Dave Airlie
This reverts commit 83c0bcb694be31dcd6c04bdd935b96a95a0af548. Lucas pointed out this was a mistake, and I missed the discussion, so just revert it out to save a rebase. Signed-off-by: Dave Airlie <airlied@redhat.com>
2012-12-30drm: tegra: program only one window during modesetLucas Stach
The intention is to program exactly WIN_A, not WIN_A and possibly others. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Dave Airlie <airlied@redhat.com>
2012-12-30drm: tegra: clean out old gem prototypesLucas Stach
There is no gem.c anymore, those functions are implemented by the drm_cma_helpers now. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Dave Airlie <airlied@redhat.com>
2012-12-30drm: tegra: remove redundant tegra2_tmds_config entryLucas Stach
The 720p and 1080p entries are completely redundant, as we are matching the table entries against <=pclk. Also generalize the comment, as we are using those table entries even when driving other modes than the standard TV ones.

2012-12-30drm: tegra: protect DC register access with mutexLucas Stach
Window properties are programmed through a shared aperture and have to happen atomically. Also we do the read-update-write dance on some of the shared regs. To make sure that different functions don't stumble over each other protect the register access with a mutex.

2012-12-30drm: tegra: don't leave clients host1x member uninitializedLucas Stach
No real problem for now, as nothing is using this, but leaving it unitialized is asking for trouble later on. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Dave Airlie <airlied@redhat.com>

2012-11-28drm: tegra: Add Tegra30 supportThierry Reding
Add support for host1x, the display controllers and HDMI on the Tegra30 SoC. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de> Tested-by: Stephen Warren <swarren@nvidia.com> Tested-by: Mark Zhang <markz@nvidia.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2012-11-28drm: tegra: Use framebuffer pitch as line strideThierry Reding
Instead of using the stride derived from the display mode, use the pitch associated with the currently active framebuffer. This fixes a bug where the LCD display content would be skewed when enabling HDMI with a video mode different from that of the LCD.

2012-11-20drm: tegra: Add HDMI supportThierry Reding
This commit adds support for the HDMI output on the Tegra20 SoC. Only one such output is available, but it can be driven by either of the two display controllers. A lot of work on this patch has been contributed by NVIDIA's Mark Zhang <markz@nvidia.com> and many other people at NVIDIA were very helpful in getting the HDMI support and surrounding infrastructure to work.

2012-11-20drm: Add NVIDIA Tegra20 supportThierry Reding
This commit adds a KMS driver for the Tegra20 SoC. This includes basic support for host1x and the two display controllers found on the Tegra20 SoC. Each display controller can drive a separate RGB/LVDS output.
