drm/tegra: sor: Add Tegra186 support

2017-12-13T13:36:36Z

The SOR found on Tegra186 is very similar to the one found on Tegra210 and earlier. However, due to some changes in the display architecture, some programming sequences have changed and some register have moved around. Signed-off-by: Thierry Reding

Merge airlied/drm-next into drm-misc-next

2017-11-21T13:17:56Z

Bake in the conflict between the drm_print.h extraction and the addition of DRM_DEBUG_LEASES since we lost it a few too many times. Also fix a new use of drm_plane_helper_check_state in msm to follow Ville's conversion in commit a01cb8ba3f6282934cff65e89ab36b18b14cbe27 Author: Ville Syrjälä Date: Wed Nov 1 22:16:19 2017 +0200 drm: Move drm_plane_helper_check_state() into drm_atomic_helper.c Acked-by: Ville Syrjälä Signed-off-by: Daniel Vetter

drm/drivers: drop redundant drm_edid_to_eld() calls

2017-11-07T15:43:35Z

drm_add_edid_modes() now fills in the ELD automatically, so the calls to drm_edid_to_eld() are redundant. Remove them. All the other places are obvious, but nv50 has detached drm_edid_to_eld() from the drm_add_edid_modes() call.

drm/tegra: hdmi: Add cec-notifier support

2017-10-20T12:19:54Z

In order to support CEC the HDMI driver has to inform the CEC driver whenever the physical address changes. So when the EDID is read the CEC driver has to be informed and whenever the hotplug detect goes away. This is done through the cec-notifier framework. The link between the HDMI driver and the CEC driver is done through the hdmi-phandle property in the tegra-cec node in the device tree. Signed-off-by: Hans Verkuil Signed-off-by: Thierry Reding

Merge tag 'drm/tegra/for-4.8-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next

2016-07-16T01:23:50Z

drm/tegra: Changes for v4.8-rc1 This set of changes contains a bunch of cleanups to the host1x driver as well as the addition of a pin controller for DPAUX, which is required by boards to configure the DPAUX pads in AUX mode (for DisplayPort) or I2C mode (for HDMI and DDC). Included is also a bit of rework of the SOR driver in preparation to add DisplayPort support as well as some refactoring and cleanup. Finally, all output drivers are converted to runtime PM, which greatly simplifies the handling of clocks and resets. * tag 'drm/tegra/for-4.8-rc1' of git://anongit.freedesktop.org/tegra/linux: (35 commits) drm/tegra: sor: Reject HDMI 2.0 modes drm/tegra: sor: Prepare for generic PM domain support drm/tegra: dsi: Prepare for generic PM domain support drm/tegra: sor: Make XBAR configurable per SoC drm/tegra: sor: Use sor1_src clock to set parent for HDMI dt-bindings: display: tegra: Add source clock for SOR drm/tegra: sor: Implement sor1_brick clock drm/tegra: sor: Implement runtime PM drm/tegra: hdmi: Implement runtime PM drm/tegra: dsi: Implement runtime PM drm/tegra: dc: Implement runtime PM drm/tegra: hdmi: Enable audio over HDMI drm/tegra: sor: Do not support deep color modes drm/tegra: sor: Extract tegra_sor_mode_set() drm/tegra: sor: Split out tegra_sor_apply_config() drm/tegra: sor: Rename tegra_sor_calc_config() drm/tegra: sor: Factor out tegra_sor_set_parent_clock() drm/tegra: dpaux: Add pinctrl support dt-bindings: Add bindings for Tegra DPAUX pinctrl driver drm/tegra: Prepare DPAUX for supporting generic PM domains ...

drm/tegra: hdmi: Enable audio over HDMI

2016-07-04T09:34:31Z

In order to use the HDA codec to forward audio data to the HDMI codec it needs the ELD that is parsed from the monitor's EDID. Also implement an interoperability mechanism between the HDA controller and the HDMI codec. This uses vendor-defined scratch registers to pass data from the HDMI codec driver to the HDMI driver (that implements the receiving end of the HDMI codec). A custom format is used to pass audio sample rate and channel count to the HDMI driver. Signed-off-by: Thierry Reding

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/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
