drm/tegra: dsi: Restore DPMS

2015-08-13T11:49:23+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: dsi: Add Tegra210 support

2015-08-13T11:47:45+00:00

The DSI host controller hasn't changed from Tegra132 to Tegra210, but different characterization parameters may be required. Signed-off-by: Thierry Reding

drm/tegra: dsi: Add Tegra132 support

2015-08-13T11:47:44+00:00

The DSI host controller hasn't changed from Tegra124 to Tegra132, but different characterization parameters may be required. Signed-off-by: Thierry Reding

drm/tegra: dsi: Add Tegra124 support

2015-08-13T11:47:44+00:00

The DSI host controller hasn't changed from Tegra114 to Tegra124, but different characterization parameters may be required. Signed-off-by: Thierry Reding

drm/tegra: dsi: Use proper back-porch for non-sync video mode

2015-08-13T11:47:44+00:00

In video modes without sync pulses, the horizontal back-porch needs to include the horizontal sync width. Signed-off-by: Thierry Reding

drm/tegra: dc: Unify enabling the display controller

2015-01-27T09:14:58+00:00

Previously output drivers would enable continuous display mode and power up the display controller at various points during the initialization. This is suboptimal because it accesses display controller registers in output drivers and duplicates a bit of code. Move this code into the display controller driver and enable the display controller as the final step of the ->mode_set_nofb() implementation. Signed-off-by: Thierry Reding

drm/tegra: Remove unused ->mode_fixup() callbacks

2015-01-27T09:14:56+00:00

All output drivers have now been converted to use the ->atomic_check() callback, so the ->mode_fixup() callbacks are no longer used. Signed-off-by: Thierry Reding

drm/tegra: dsi: Implement ->atomic_check()

2015-01-27T09:14:53+00:00

The implementation of the ->atomic_check() callback precomputes all parameters to check if the given configuration can be applied. If so the precomputed values are stored in the atomic state object for the encoder and applied during modeset. In that way the modeset no longer needs to perform any checking but simply program values into registers. Signed-off-by: Thierry Reding

drm/tegra: Atomic conversion, phase 2

2015-01-27T09:14:51+00:00

Hook up the default ->reset() and ->atomic_duplicate_state() helpers. This ensures that state objects are properly created and framebuffer reference counts correctly maintained. Signed-off-by: Thierry Reding

drm/tegra: Atomic conversion, phase 1

2015-01-27T09:14:50+00:00

Implement initial atomic state handling. Hook up the CRTCs, planes' and connectors' ->atomic_destroy_state() callback to ensure that the atomic state objects don't leak. Furthermore the CRTC now implements the ->mode_set_nofb() callback that is used by new helpers to implement ->mode_set() and ->mode_set_base(). These new helpers also make use of the new plane helper functions which the driver now provides. Signed-off-by: Thierry Reding
