Name the fields of the SOR_SEQ_CTL register consistently. Signed-off-by: Thierry Reding

drm/tegra: hdmi: Resets are synchronous

2015-04-02T16:49:22Z

Resets on Tegra are synchronous, so keep the clock enabled while asserting the reset. Signed-off-by: Thierry Reding

drm/tegra: hdmi: Explicitly set clock rate

2015-02-19T13:21:25Z

Recent changes in the clock framework have caused a behavioural change in that clocks that have not had their rate set explicitly will now be reset to their initial rate (or 0) when the clock is released. This is triggered in the deferred probing path, resulting in the clock running at a wrong frequency after the successful probe. This can be easily fixed by setting the rate explicitly rather than by relying on the implicit rate inherited by the parent. Tested-by: Tomeu Vizoso 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: hdmi: 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

2015-01-27T09:14:49Z

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

drm/tegra: Remove remnants of the output midlayer

2015-01-27T09:14:49Z

The tegra_output midlayer is now completely gone and output drivers use it purely as a helper library. Signed-off-by: Thierry Reding
