remove abs64()

2015-11-09T23:11:24+00:00

Switch everything to the new and more capable implementation of abs(). Mainly to give the new abs() a bit of a workout.

drm/tegra: sor: Add HDMI support

2015-08-13T11:49:37+00:00

The SOR1 introduced on Tegra210 supports HDMI 2.0 and DisplayPort. Add HDMI support and name the debugfs node after the type of SOR. The SOR introduced with Tegra124 is known simply as "sor", whereas the additional SOR found on Tegra210 is known as "sor1". Signed-off-by: Thierry Reding

drm/tegra: sor: Add Tegra210 eDP support

2015-08-13T11:49:36+00:00

The SOR found on Tegra210 is very similar to the version found on Tegra124, except that it no longer supports LVDS. Signed-off-by: Thierry Reding

drm/tegra: sor: Restore DPMS

2015-08-13T11:49:35+00:00

In order to restore DPMS with atomic mode-setting, move all code from the ->mode_set() callback into ->enable(). At the same time, rename the ->prepare() callback to ->disable() to use the names preferred by atomic mode-setting. This simplifies the calling sequence and will allow DPMS to use runtime PM in subsequent patches. Signed-off-by: Thierry Reding

drm/tegra: sor: Use DRM debugfs infrastructure for CRC

2015-08-13T11:47:57+00:00

Instead of duplicating most of the code to set up a debugfs file, use the existing DRM core debugfs infrastructure instead. Signed-off-by: Thierry Reding

drm/tegra: sor: Write correct head state registers

2015-08-13T11:47:56+00:00

The head state registers are per head, so they must be properly indexed. This has worked fine so far because all boards with eDP use it as the primary output, so it is very likely to end up attached to head 0. Signed-off-by: Thierry Reding

drm/tegra: sor: Constify display mode

2015-08-13T11:47:56+00:00

The data structure is always only read, never written, and can hence be referred to by a const pointer. Signed-off-by: Thierry Reding

drm/tegra: sor: Reset the correct debugfs fields

2015-08-13T11:47:55+00:00

When tearing down debugfs support, make sure to reset the fields to NULL in the correct order, otherwise the debugfs root will not be properly removed. Signed-off-by: Thierry Reding

drm/tegra: sor: Set minor after debugfs initialization

2015-08-13T11:47:53+00:00

The DRM minor is needed to teardown debugfs, so it needs to be tracked to prevent a crash on driver removal. Signed-off-by: Thierry Reding

drm/tegra: sor: Provide error messages in probe

2015-08-13T11:47:51+00:00

When probing the SOR device fails, output proper error messages to help diagnose the cause of the failure. Signed-off-by: Thierry Reding
