drm/tegra: hub: Use private object for global state

2018-03-16T23:03:36Z

Rather than subclass the global atomic state to store the hub display clock and rate, create a private object and store this data in its state. Signed-off-by: Thierry Reding

Merge tag 'drm/tegra/for-4.16-rc1-fixes' of git://anongit.freedesktop.org/tegra/linux into drm-next

2018-01-12T01:46:19Z

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 ...

drm/tegra: Use IOMMU groups

2017-12-21T13:52:36Z

In order to support IOMMUs more generically and transparently handle the ARM SMMU on Tegra186, move to using groups instead of devices for domain attachment. An IOMMU group is a set of devices that share the same IOMMU domain and is therefore a good match to represent what Tegra DRM needs. Signed-off-by: Thierry Reding

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

drm/tegra: Add Tegra186 display hub support

2017-12-13T13:16:37Z

The display architecture has changed in several significant ways with the new Tegra186 SoC. Shared between all display controllers is a set of common resources referred to as the display hub. The hub generates accesses to memory and feeds them into various composition pipelines, each of which being a window that can be assigned to arbitrary heads. Atomic state is subclassed in order to track the global bandwidth requirements and select and adjust the hub clocks appropriately. The plane code is shared to a large degree with earlier SoC generations, except where the programming differs. Signed-off-by: Thierry Reding

drm/tegra: Use atomic commit helpers

2017-12-13T12:42:10Z

There's no reason not to use them, and they already get all the semantics right, so rip out all of the custom code and replace it by the helpers. Signed-off-by: Thierry Reding

drm/tegra: Use drm_fb_helper_lastclose() and _poll_changed()

2017-12-08T12:09:27Z

This driver can use drm_fb_helper_lastclose() as its .lastclose callback. It can also use drm_fb_helper_output_poll_changed() as its .output_poll_changed callback.

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
