Revert "drm: tegra: protect DC register access with mutex"

2012-12-30T11:58:20Z

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

drm: tegra: program only one window during modeset

2012-12-30T04:01:35Z

The intention is to program exactly WIN_A, not WIN_A and possibly others. Signed-off-by: Lucas Stach Signed-off-by: Dave Airlie

drm: tegra: clean out old gem prototypes

2012-12-30T04:01:34Z

There is no gem.c anymore, those functions are implemented by the drm_cma_helpers now. Signed-off-by: Lucas Stach Signed-off-by: Dave Airlie

drm: tegra: remove redundant tegra2_tmds_config entry

2012-12-30T04:01:33Z

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. Signed-off-by: Lucas Stach Signed-off-by: Dave Airlie

drm: tegra: protect DC register access with mutex

2012-12-30T04:01:33Z

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. Signed-off-by: Lucas Stach Signed-off-by: Dave Airlie

drm: tegra: don't leave clients host1x member uninitialized

2012-12-30T04:01:32Z

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 Signed-off-by: Dave Airlie

drm: tegra: fix front_porch <-> back_porch mixup

drm: tegra: Add Tegra30 support

drm: tegra: Use framebuffer pitch as line stride

2012-11-28T10:05:46Z

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.

drm: tegra: Add HDMI support

2012-11-20T05:43:53Z

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 and many other people at NVIDIA were very helpful in getting the HDMI support and surrounding infrastructure to work.
