drm: Nuke drm_atomic_helper_connector_dpms

2017-08-08T12:48:48Z

It's dead code, the core handles all this directly now. The only special case is nouveau and tda988x which used one function for both legacy modeset code and -nv50 atomic world instead of 2 vtables. But amounts to exactly the same. v2: Rebase over the panel/brideg refactorings in stm/ltdc.

drm: tegra: Rely on the default ->best_encoder() behavior

2016-06-10T15:24:48Z

All outputs have a 1:1 relationship between connectors and encoders and the driver is relying on the atomic helpers: we can drop the custom ->best_encoder() implementation and let the core call drm_atomic_helper_best_encoder() for us.

drm: Pass 'name' to drm_encoder_init()

2015-12-11T08:13:20Z

drm/tegra: rgb: Restore DPMS

2015-08-13T11:48:54Z

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 code to use runtime PM in subsequent patches. While at it, remove the enabled field that hasn't been used since the demidlayering of the output drivers done in preparation for the atomic mode-setting conversion. Signed-off-by: Thierry Reding

drm/tegra: dc: Unify enabling the display controller

2015-01-27T09:14:58Z

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

2015-01-27T09:14:56Z

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: rgb: Implement ->atomic_check()

2015-01-27T09:14:53Z

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

2015-01-27T09:14:51Z

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

2015-01-27T09:14:50Z

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

drm/tegra: Output cleanup functions cannot fail

The tegra_output_exit() and tegra_output_remove() functions cannot fail, so make them return void. Signed-off-by: Thierry Reding
