2018-03-15drm/tegra: plane: Correct legacy blendingDmitry Osipenko
Keep old 'dependent' state of unaffected planes, this way new state takes into account current state of unaffected planes. Fixes: ebae8d07435a ("drm/tegra: dc: Implement legacy blending") Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2018-03-15drm/tegra: plane: Fix RGB565 format on older TegraThierry Reding
The opaque/alpha format conversion code is currently only looking at XRGB formats because they have an equivalent ARGB format. The opaque format for RGB565 is RGB565 itself, much like the YUV formats map to themselves.

2018-01-08drm/tegra: dc: Restore YUV overlay supportThierry Reding
Commit ebae8d07435a ("drm/tegra: dc: Implement legacy blending") broke support for YUV overlays by accident. The reason is that YUV formats are considered opaque because they have no alpha component, but on the other hand no corresponding format with an alpha component can be returned. In the case of YUV formats, the opaque format is the same as the alpha format, so add the special case to restore YUV overlay support.

2017-12-21drm/tegra: dc: Implement legacy blendingThierry Reding
This implements alpha blending on legacy display controllers (Tegra20, Tegra30 and Tegra114). While it's theoretically possible to support the zpos property to enable userspace to specify the Z-order of each plane individually, this is not currently supported and the same fixed Z- order as previously defined is used. Reverts commit 71835caa00e8 ("drm/tegra: fb: Force alpha formats") since the opaque formats are now supported.

2017-12-21drm/tegra: dc: Support more formatsThierry Reding
Also, split up formats into per-SoC lists because not all generations support all of them. Note that the list is now exhaustive for all RGB formats, but not for YUV and indexed formats. Signed-off-by: Thierry Reding <treding@nvidia.com>
2017-12-13drm/tegra: Support ARGB and ABGR formatsThierry Reding
These formats can easily be supported on all generations of Tegra. Note that the XRGB and XBGR formats that we supported were in fact using the ARGB and ABGR Tegra formats. This happened to work in cases where no alpha was being considered. This change is also a fix for those formats. Signed-off-by: Thierry Reding <treding@nvidia.com>
2017-12-13drm/tegra: Move common plane code to separate fileThierry Reding
Subsequent patches will add support for Tegra186 which has a different architecture and needs different plane code but which can share a lot of code with earlier Tegra support. Signed-off-by: Thierry Reding <treding@nvidia.com>
