Add support for the Extron DA HD 4K Plus series of 4K HDMI
Distrubution Amplifiers (aka HDMI Splitters).
These devices support CEC and this driver adds support for the
CEC protocol for both the input and all outputs (2, 4 or 6 outputs,
depending on the model).
It also exports the EDID from the outputs and allows reading and
setting the EDID of the input.

The current driver sets the response buffer threshold value to 1
(N+1, 2 DWORDS) in the QUEUE THRESHOLD register. However, the AMD
I3C controller only generates interrupts when the response buffer
threshold value is set to 0 (1 DWORD).
Therefore, a quirk is added to set the response buffer threshold value
to 0.

It's observed that, when the first 4GB of system memory was reserved, all
VCMDQ allocations failed (even with the smallest qsz in the last attempt):
arm-smmu-v3: found companion CMDQV device: NVDA200C:00
arm-smmu-v3: option mask 0x10
arm-smmu-v3: failed to allocate queue (0x8000 bytes) for vcmdq0
acpi NVDA200C:00: tegra241_cmdqv: Falling back to standard SMMU CMDQ
arm-smmu-v3: ias 48-bit, oas 48-bit (features 0x001e1fbf)
arm-smmu-v3: allocated 524288 entries for cmdq
arm-smmu-v3: allocated 524288 entries for evtq
arm-smmu-v3: allocated 524288 entries for priq
This is because the 4GB reserved memory shifted the entire DMA zone from a
lower 32-bit range (on a system without the 4GB carveout) to higher range,
while the dev->coherent_dma_mask was set to DMA_BIT_MASK(32) by default.
The dma_set_mask_and_coherent() call is done in arm_smmu_device_hw_probe()
of the SMMU driver. So any DMA allocation from tegra241_cmdqv_probe() must
wait until the coherent_dma_mask is correctly set.
Move the vintf/vcmdq structure initialization routine into a different op,
"init_structures". Call it at the end of arm_smmu_init_structures(), where
standard SMMU queues get allocated.
Most of the impl_ops aren't ready until vintf/vcmdq structure are init-ed.
So replace the full impl_ops with an init_ops in __tegra241_cmdqv_probe().
And switch to tegra241_cmdqv_impl_ops later in arm_smmu_init_structures().
Note that tegra241_cmdqv_impl_ops does not link to the new init_structures
op after this switch, since there is no point in having it once it's done.

Variable 'sbrn' is used to store the Serial Bus Release Number, which is
then only used for a debug message. Thus, 'sbrn' can be a local variable
and assigned after the primary HCD check. The SBRN debug message is only
printed when a primary HCD is setup.

Variables 'max_slots', 'max_ports', 'isoc_threshold' and 'event_ring_max'
are never set or used. Thus, remove them.

Completion codes 'COMP_SUCCESS' and 'COMP_SHORT_PACKET' are the most
frequently encountered completion codes. Typically, these codes do not
trigger a default debug message but rather a warning that indicates a
potential issue. This behavior is consistent across all transfer types
with the exception of Bulk transfers. To reduce unnecessary log clutter,
remove the Bulk 'COMP_SHORT_PACKET' debug message.

The removed debug messages trigger each time an isoc frame is handled.
In case of an error, a dedicated debug message exists.
For example, a 60fps USB camera will trigger the debug message every 0.6s.

Make sure we move the requests from the read_queue to the end of the
read_pool list, avoiding looping and using the same one request all
the time.

Don't flush all pending DbC data requests when an endpoint halts.
An endpoint may halt and xHC DbC triggers a STALL error event if there's
an issue with a bulk data transfer. The transfer should restart once xHC
DbC receives a ClearFeature(ENDPOINT_HALT) request from the host.
Once xHC DbC restarts it will start from the TRB pointed to by dequeue
field in the endpoint context, which might be the same TRB we got the
STALL event for. Turn the TRB to a no-op in this case to make sure xHC
DbC doesn't reuse and tries to retransmit this same TRB after we already
handled it, and gave its corresponding data request back.
Other STALL events might be completely bogus.
Lukasz Bartosik discovered that xHC DbC might issue spurious STALL events
if hosts sends a ClearFeature(ENDPOINT_HALT) request to non-halted
endpoints even without any active bulk transfers.
Assume STALL event is spurious if it reports 0 bytes transferred, and
the endpoint stopped on the STALLED TRB.
Don't give back the data request corresponding to the TRB in this case.
The halted status is per endpoint. Track it with a per endpoint flag
instead of the driver invented DbC wide DS_STALLED state.
DbC remains in DbC-Configured state even if endpoints halt. There is no
Stalled state in the DbC Port state Machine (xhci section 7.6.6)
