Some (particularly SMD_RPM, a.k.a non-RPMh) SoCs implement A6XX GPUs
but don't implement the associated GMUs. This is due to the fact that
the GMU directly pokes at RPMh. Sadly, this means we have to take care
of enabling & scaling power rails, clocks and bandwidth ourselves.
Reuse existing
These SKUs don't support the feature. Disable it to make the GPU stop
crashing after almost each and every submission - the received data on
the GPU end was simply incomplete in garbled, resulting in almost nothing
being executed properly.

Currently we only utilize the OPP table connected to the GPU for
getting (available) frequencies. We do however need to scale the
voltage rail(s) accordingly to ensure that we aren't trying to
run the GPU at 1GHz with a VDD_LOW vote, as that would result in
an otherwise inexplainable hang.
Tell
A619_holi is implemented on at least two SoCs: SM4350 (holi) and SM6375
(blair). This is what seems to be a first occurrence of this happening,
but it's easy to overcome by guarding the SoC-specific fuse values with
of_machine_is_compatible(). Do just that to enable frequency limiting
on these
A610 is implemented on at least three SoCs: SM6115 (bengal), SM6125
(trinket) and SM6225 (khaje). Trinket does not support speed binning
(only a single SKU exists) and we don't yet support khaje upstream.
Hence, add a fuse mapping table for bengal to allow for per-chip
frequency limiting.
One of the protected ranges was too small (compared to the data we
have downstream). Fix it.

On GMU-equipped GPUs, the GMU requests appropriate bandwidth votes
for us. This is however not the case for the other GPUs. Add the
dev_pm_opp_of_find_icc_paths() call to let the OPP framework handle
bus voting as part of power level setting.

The GPU can only be one at a time. Turn a series of ifs into if +
elseifs to save some CPU cycles.

Hi,
You seem to have sent this twice, perhaps to adjust the To/CC list. I
think I've picked the right one to reply to, but it's usually nice to
use a "v2" notation or otherwise put a comment somewhere in the email.

Since, hot plugging eDP displays isn't supported, it is sufficient for
us to warn about the lack of a connected display once. So, use ASSERT()
in dce110_edp_wait_for_hpd_ready() instead of DC_LOG_WARNING().
