drm/tegra: dc: Don't clean up unused display controller

2018-11-29T16:25:32Z

Display controllers that don't own any windows and which therefore aren't currently being assigned a primary plane are not registered as a CRTC with the DRM framework. They request neither a syncpoint nor an interrupt because they don't use them, so avoid cleaning up those resources. Signed-off-by: Thierry Reding

drm/tegra: dc: Add Tegra194 support

2018-09-26T14:04:39Z

The display controllers found on Tegra194 are almost identical to those found on Tegra186. Signed-off-by: Thierry Reding

drm/tegra: dc: Do not register DC without primary plane

2018-09-26T14:03:51Z

Tegra194 contains a fourth display controller that does not own any windows. Therefore, we cannot currently assign a primary plane to it which causes KMS to eventually crash. Do not register the display controller if it owns no windows to work around this. Note that we still have to enable and probe the display controller because for some reason all display controllers need to be powered (and/or clocked) before any registers can be accessed in any of the display controllers.

driver core: Rename flag AUTOREMOVE to AUTOREMOVE_CONSUMER

2018-07-09T10:14:31Z

Now that we want to add another flag to autoremove the device link on supplier unbind, it's fair to rename the existing flag from DL_FLAG_AUTOREMOVE to DL_FLAG_AUTOREMOVE_CONSUMER so that we can add similar flag for supplier later. And, while we are touching device.h, fix a doc build warning. Signed-off-by: Vivek Gautam Reviewed-by: Ulf Hansson Signed-off-by: Rafael J. Wysocki

drm/tegra: dc: Support rotation property

2018-05-18T19:56:21Z

Currently only the DRM_MODE_REFLECT_Y rotation is supported. The driver already supports reflection on the Y axis via a custom flag which is not very useful because it requires custom userspace. Add the standard rotation property that supports 0 degree rotation and Y axis reflection for primary and overlay planes to provide a better interface than the custom flag. v2: keep custom flag for ABI compatibility (Dmitry) Reviewed-by: Dmitry Osipenko Tested-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: dc: Rename supports_blending to has_legacy_blending

2018-05-17T12:08:44Z

Older Tegra chips do support blending as well. Rename the SoC info entry .supports_blending to .has_legacy_blending to eliminate the confusion. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: plane: Implement zpos plane property for older Tegras

2018-05-17T12:08:44Z

Older Tegra's do not support plane's Z position handling in hardware, but the hardware provides knobs to implement it in software. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: dc: Enable plane scaling filters

2018-05-17T12:08:44Z

Currently resized plane produces a "pixelated" image which doesn't look nice, especially in a case of a video overlay. Enable scaling filters that significantly improve image quality of a scaled overlay. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: Refactor IOMMU attach/detach

2018-05-17T12:08:40Z

Attaching to and detaching from an IOMMU uses the same code sequence in every driver, so factor it out into separate helpers. Reviewed-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: dc: Free syncpoint on errors

2018-05-04T15:07:06Z

If an error happens during display controller initialization, the host1x syncpoint previously requested would be leaked. Properly clean up the syncpoint along with the other resources. Reviewed-by: Dmitry Osipenko Signed-off-by: Thierry Reding
