This patch does not change current behaviour. The driver's job timeout handler now returns status indicating back to the DRM layer whether the device (GPU) is no longer available, such as after it's been unplugged, or whether all is normal, i.e. current behaviour. All drivers which make use of the drm_sched_backend_ops' .timedout_job() callback have been accordingly renamed and return the would've-been default value of DRM_GPU_SCHED_STAT_NOMINAL to restart the task's timeout timer--this is the old behaviour, and is preserved by this patch. v2: Use enum as the status of a driver's job timeout callback method. v3: Return scheduler/device information, rather than task information.

We introduced the BCM2711 support to the vc4 HDMI controller with 5.10, but this was lacking any of the interrupts of the CEC controller so we have to deal with the backward compatibility. Do so by simply ignoring the CEC setup if the DT doesn't have the interrupts property. Reviewed-by:

The BCM2711 has two different interrupt sources to transmit and receive CEC messages, provided through an external interrupt chip shared between the two HDMI interrupt controllers. The rest of the CEC controller is identical though so we need to change a bit the code organisation to share the code as much as possible, yet still allowing to register independent handlers.

While the BCM2835 had the CEC clock derived from the HSM clock, the BCM2711 has a dedicated parent clock for it. Let's introduce a separate clock for it so that we can handle both cases. Reviewed-by:

Maxime Ripard authored
As part of the enable sequence we might change the HSM clock rate if the pixel rate is different than the one we were already dealing with. On the BCM2835 however, the CEC clock derives from the HSM clock so any rate change will need to be reflected in the CEC clock divider to output 40kHz.

Maxime Ripard authored
The CEC clock divider needs to output a frequency of 40kHz from the HSM rate on the BCM2835.

Currently we call cec_phys_addr_invalidate on a hotplug deassert. That may be due to a TV power cycling, or an AVR being switched on (and switching edid).

Dom Cobley authored
The code prior to 311e305f ("drm/vc4: hdmi: Implement a register layout abstraction") was relying on the fact that the register offset was incremented by 4 for each readl call.

Additional compatible strings have been added in DT source for the i.MX6SL, i.MX6SLL, i.MX6UL and i.MX7D without updating the bindings. Most of the upstream DT sources use the fsl,imx28-lcdif compatible string, which mostly predates the realization that the LCDIF in the i.MX6 and newer SoCs have extra features compared to the i.MX28. Update the bindings to add the missing compatible strings, with the correct fallback values. This fails to validate some of the upstream DT sources. Instead of adding the incorrect compatible fallback to the binding, the sources should be updated separately. Signed-off-by:

Convert the mxsfb binding to YAML. The deprecated binding is dropped, as neither the DT sources nor the driver support it anymore. The converted binding is named fsl,lcdif.yaml to match the usual bindings naming scheme. The compatible strings are messy, and DT sources use different kinds of combination of documented and undocumented values. Keep it simple for now, and update the example to make it valid. Aligning the binding with the existing DT sources will be performed separately. Signed-off-by:

The explicit out-fences in crtc are signaled as part of vblank event, indicating all framebuffers present on the Atomic Commit request are scanned out on the screen. Though the fence signal and the vblank event notification happens at the same time, triggered by the same hardware vsync event, the timestamp set in both are different. With drivers supporting precise vblank timestamp the difference between the two timestamps would be even higher. This might have an impact on use-mode frameworks using these fence timestamps for purposes other than simple buffer usage. For instance, the Android framework [1] uses the retire-fences as an alternative to vblank when frame-updates are in progress. Set the fence timestamp during send vblank event using a new drm_send_event_timestamp_locked variant to avoid discrepancies. [1] https://android.googlesource.com/platform/frameworks/native/+/master/ services/surfaceflinger/Scheduler/Scheduler.cpp#397 Changes in v2: - Use drm_send_event_timestamp_locked to update fence timestamp - add more information to commit text Changes in v3: - use same backend helper function for variants of drm_send_event to avoid code duplications Changes in v4: - remove WARN_ON from drm_send_event_timestamp_locked Signed-off-by:
