In order to enable wider testing of the Iris driver on the HFI Gen1
platforms enable support for Qualcomm SM8350 and SC8280XP platforms.
Note, this has been tested only with the Iris driver. Venus driver fails
to boot the Iris core on SM8350 pointing out the UC_REGION error.
Note, the firmware for SM8250 isn't compatible with SM8350 (nor with
SC8280XP). Please use corresponding firmware, extracted from the Windows
/ Android data.
On SM8350 with the Iris driver:

Changes in v4:
- Changed compat strings to use -iris instead of -venus (Konrad,
Dikshita)
- Dropped separate schema file, switched to SM8250 schema
- Dropped driver bits, it's covered by compatible string now
- Link to v3: https://lore.kernel.org/r/20260125-iris-sc8280xp-v3-0-d21861a9ea33@oss.qualcomm.com
Changes in v3:
- Add missing header, sorry.
- Link to v2: https://lore.kernel.org/r/20260125-iris-sc8280xp-v2-0-552cdc3ea691@oss.qualcomm.com
Changes in v2:
- Added missing chunk, including sm8350-videocc.h, lost in rebases.

Venus with the SM8250-related fixes should probably work too. Anyway, I
hope that the series switching SM8250 / SC7280 from Venus to Iris will
finally land...

Thanks for the additional testing!
This might be:
- A bug in the firmware
- A bug in the Gen1 support in the Iris driver.
- A bug in totem (heh).
Would you mind sharing details, which video were you trying to play (at
least, the codec that it used, please).
Also, does it kill the playback afterwards? Can you start another
playing stream afterwards?

And this points out an error in the Iris driver. Quoting the comment:
/*
* If done_list is not empty, then start_streaming() didn't call
* vb2_buffer_done(vb, VB2_BUF_STATE_QUEUED) but STATE_ERROR or
* STATE_DONE.
*/
Dikshita, Vikash, would you mind checking it out?

I do not have a ton of videos to test, so I just used 2 that are on my system.
This is not just with totem, showtime shows the same issue. If I let the video
play, it plays just fine, however, if I attempt to skip forward, back, or even
play *after* the video has played, then I see the smmu fault
arm-smmu 15000000.iommu: Unhandled context fault: fsr=0x402, iova=0xd51e3e00, fsynr=0x600002, cbfrsynra=0x2a00, cb=6

qcom-iris aa00000.video-codec: sys error (type: 1, session id:ff, data1:1, data2:deadbead)
If I exit and re-launch totem, it will play the video through, but again, if I
attempt to skip forward, back or play once it has finished the video, then again
the smmu fault occurs.
totem and showtime both use gstreamer, and show the issue. showtime replaces
totem as the media player on modern gnome systems. mpv and vlc do *not* show
the issue, but they also do not appear to use iris/venus at all.
Totem is version 43.2-11
Showtime is version 50~rc2
Host system is Kali, which is essentially Debian Testing.
