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

2012-12-30T11:58:20+00:00

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.

drm: tegra: program only one window during modeset

2012-12-30T04:01:35+00:00

The intention is to program exactly WIN_A, not WIN_A and possibly
others.

drm: tegra: clean out old gem prototypes

2012-12-30T04:01:34+00:00

There is no gem.c anymore, those functions are implemented by the
drm_cma_helpers now.

drm: tegra: remove redundant tegra2_tmds_config entry

2012-12-30T04:01:33+00:00

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.

drm: tegra: protect DC register access with mutex

2012-12-30T04:01:33+00:00

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.

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

2012-12-30T04:01:32+00:00

No real problem for now, as nothing is using this, but leaving it
unitialized is asking for trouble later on.

drm: tegra: Use framebuffer pitch as line stride

2012-11-28T10:05:46+00:00

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

2012-11-20T05:43:53+00:00

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.
