This patch adapts the panfrost pre-defined thresholds change [0] to the lima driver to improve real-world performance. The upthreshold value has been set to ramp GPU frequency to max freq faster (compared to panfrost) to compensate for the lower overall performance of utgard devices.

pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in a reference leak here.

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.

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.

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.

The CEC clock divider needs to output a frequency of 40kHz from the HSM rate on the BCM2835. The driver used to have a fixed frequency for it, but that changed for the BCM2711 and we now need to compute it dynamically to maintain the proper rate.
