Re: [PATCH v2 0/9] media: camss: add SM8750 support

[Qianhui Xu]

Hi Krzysztof,

first, the honest part: I work on this board alone, my English is not
good enough to write upstream mail unaided, so I draft with an AI assistant
and edit it myself; the content and the decisions are mine.  My previous
message in this thread was unclear and that is on me.

You asked what I was referring to.  It was the SM8750 camss series
([PATCH v2 0/9] from 28 October) and your comments about splitting the
enablement from the board DTS.  My reply quoted another thread and did not
say which question it answered, so the thread read as unrelated.  Sorry.

The state of that work now:
 - the SM8750 camss enablement is not mine to push; Bryan has said it goes
   through Hangxiang's series.  I am not resending it.
 - what remains from my side are two fixes on the existing code, sent
   separately as [PATCH v2 0/2]: the csid power-on unwind and the VFE
   stream start/stop handling.
 - I dropped the DMA-contiguity patch completely.  Bryan measured plane0
   with five physical breaks and no IOVA breaks, and it works; my check
   tested the IOVA while claiming physical contiguity, so it was wrong even
   before that measurement.  The prepare hook it added had no user.
 - Loic's shape for the streaming fix is taken: one helper for the
   subdevice walk, the remote source pad instead of pads[0], and
   v4l2_subdev_enable_streams()/disable_streams().

If you would rather see those two fixes inside Hangxiang's series instead
of standing alone, say so and I will drop them here.

Thanks for reading.
