Ah, I see, sorry :)
It looks pretty generic though, should we have a helper for this then?

HDMI 2.0 isn't just about scrambling though, YUV420 is another big
addition, and iirc you have more audio formats too.

Exactly. The mailbox controller driver should model the underlying
hardware's capabilities, not the firmware's specific usage limits.
Since the Exynos850 hardware register uses a 16-bit mask, exposing
16 hardware channels is the right move. Moving num_chans into
struct exynos_mbox_driver_data alongside the register masks for
each SoC is the cleanest approach.

There is no need to call the ACPM firmware driver. The mailbox
controller merely exposes the available pipes.

I don't remember, but regardless of how many channels the gs101 acpm
firmware actually utilizes, its hw mask is also 16 bit, so exposing
16 hardware channels for it is correct.

This race mainly occurs in GPU SMMU, where the GDSC can have an
independent vote on the Adreno SMMU. However, the GEM_NOC vote may
already have been removed by the GPU (or any consumer of adreno_smmu,
e.g gmu), unless it is explicitly voted by the GPU SMMU (which acts as a
supplier for the GPU). This mismatch can lead to SHUB timeouts or NoC
errors.
Mostly this race reported in suspend/resume cycle (when gpu/gmu devices
moves to slumber/suspend state before adreno_smmu powers down
and the later doesn't have explicit interconnect voting).
In the case of APPS SMMU, such a race is not expected for any known
use case. APPS SMMU is part of a shared infrastructure block, and its
power is typically kept enabled as long as attached master devices are
active. Therefore, explicit power-domain voting from APPS SMMU may not
be required.
Thanks,
Bibek
