* drm/tegra: hdmi: Add cec-notifier supportHans Verkuil2017-10-204-0/+19
| | | | | | | | | | | | | | | 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.

* drm/tegra: dc: Make sure to set the module clock rateThierry Reding2017-10-201-0/+5
| | | | | | | | | | When applying the PLL changes from the computed state object, make sure to set the rate of the display controller module clock. Failing to do so can yield to a situation where the parent will be set to the proper pixel clock, but the module clock will be divided down to the rate that is happened to be set to before the parent rate change.

* drm/tegra: dc: Simplify atomic plane helper functionsThierry Reding2017-10-201-28/+14
| | | | | | | | | | | Remove the tegra_dc_disable_window() function whose only purpose was to allow tegra_plane_atomic_update() to also call it. Fix that by shuffling tegra_plano_atomic_disable() to before tegra_plane_atomic_update(). While at it, also remove the overlay plane helper functions because they are exactly the same as the primary plane helper functions. Signed-off-by: Thierry Reding <treding@nvidia.com>

* gpu: host1x: syncpt: Request syncpoints per clientThierry Reding2017-10-204-4/+4
| | | | | | | | | | | | | | Rather than request syncpoints for a struct device *, request them for a struct host1x_client *. This is important because subsequent patches are going to break the assumption that host1x will always be the parent for devices requesting a syncpoint. It's also a more natural choice because host1x clients are really the only ones that will know how to deal with syncpoints. Note that host1x clients are always guaranteed to be children of host1x, regardless of their location in the device tree. Signed-off-by: Thierry Reding <treding@nvidia.com>

It should be possible to drop the per-client channel reservation and add a per-unit locking by inserting MLOCK's to the command stream to re-allow the SETCLASS opcode, but it will be much more work. Let's forbid the unit-unrelated class changes for now.
