drm/tegra: Changes for v4.16-rc1 The bulk of these changes are preparation work and addition of support for Tegra186. Currently only HDMI output (the primary output on Jetson TX2) is supported, but the hardware is also capable of doing DSI and DisplayPort. Tegra DRM now also uses the atomic commit helpers instead of the open- coded variant that was only doing half its job. As a bit of a byproduct of the Tegra186 support the driver also gained HDMI 2.0 as well as zpos property support. Along the way there are also a few patches to clean up a few things and fix minor issues. * tag 'drm/tegra/for-4.16-rc1-fixes' of git://anongit.freedesktop.org/tegra/linux: (51 commits) drm/tegra: dc: Properly cleanup overlay planes drm/tegra: dc: Fix possible_crtcs mask for planes drm/tegra: dc: Restore YUV overlay support drm/tegra: dc: Implement legacy blending drm/tegra: Correct timeout in tegra_syncpt_wait drm/tegra: gem: Correct iommu_map_sg() error checking drm/tegra: dc: Link DC1 to DC0 on Tegra20 drm/tegra: Fix non-debugfs builds drm/tegra: dpaux: Keep reset defaults for hybrid pad parameters drm/tegra: Mark Tegra186 display hub PM functions __maybe_unused drm/tegra: Use IOMMU groups gpu: host1x: Use IOMMU groups drm/tegra: Implement zpos property drm/tegra: dc: Remove redundant spinlock drm/tegra: dc: Use direct offset to plane registers drm/tegra: dc: Support more formats drm/tegra: fb: Force alpha formats drm/tegra: dpaux: Add Tegra186 support drm/tegra: dpaux: Implement runtime PM drm/tegra: sor: Support HDMI 2.0 modes ...

Cursor and overlay planes use a possible_crtcs mask based on the DC pipe number. However, DRM requires each bit in the mask to correspond to the index of the CRTC, which will be different from the DC pipe number for a configuration where the first display controller is disabled, or where a deferred probe leads to the first display controller being probed after the first.

Commit ebae8d07 ("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. Reported-by:

This series builds upon the set of fixes previously submitted to move Armada DRM closer to atomic modeset. We're nowhere near yet, but this series helps to get us closer by unifying some of the differences between the primary and overlay planes. New features added allows userspace to disable the primary plane if overlay is full screen and there's nothing obscuring the colorkey - this saves having to fetch an entire buffer containing nothing but colorkey when displaying full screen video.

It seems like the mixer can only run properly when clocked at 150MHz. In order to have something more robust than simply a fire-and-forget assigned-clocks-rate, let's put that in the code. Reviewed-by:

Maxime Ripard authored
The A83T has two video pipelines in parallel that looks quite similar to the other SoCs. The video planes are handled through a controller called the mixer, and the video signal is then passed to the timing controller (TCON). And while there is two instances of the mixers and TCONs, they have a significant number of differences. The TCONs are quite easy to deal with, one is supposed to generate TV (in the broader term, so including things like HDMI) signals, the other one LCD (so RGB, LVDS, DSI) signals. And while they are called TCON0 and TCON1 in the A83t datasheet, newer SoCs call them TCON-TV and TCON-LCD, which seems more appropriate. However, the mixers differ mostly by their capabilities, with some features being available only in the first one, or the number of planes they expose, but also through their register layout. And while the capabilities could be represented as properties, the register layout differences would need to express all the registers offsets as properties, which is usually quite bad. Especially since documentation on that hardware block is close to non-existent and we don't even have the list of all those registers in the first place. So let's call them mixer 0 and 1 in our compatibles, even though the name is pretty bad... At the moment, we only have tested the code on a board that has a single display output, so we're leaving the tcon-tv and mixer1 out. Reviewed-by:

The msm/kms driver should work even if there is no GPU device specified in DT. Currently, we get a NULL dereference crash in adreno_load_gpu since the driver assumes that priv->gpu_pdev is non-NULL. Perform an additional check on priv->gpu_pdev before trying to retrieve the msm_gpu pointer from it. v2: Incorporate Jordan's comments: - Simplify the check to share the same error message. - Use dev_err_once() to avoid an error message every time we open the drm device fd.
