Re: [PATCH 00/16] media: sun6i-csi/isp MC-centric support and cleanups

Hi,

Just a heads up. I'm currently working on sun6i-isp support for A83T (so far all
the details seem to be turning out fully compatible with V3s), and I just
noticed this patch series. I'm basing my work on top of linux-next, which
doesn't have this series yet, sadly.

I'm working with YUYV input (because that's what I have currently on my A83T
tablet with HM5065 sensor - adding bayer output to it would be another can of
worms) and I re-organized the driver to support both the dual output mode
+ rotation (can be enabled on one output only at a time, due to HW limitations).

I also added missing pipeline blocks to the driver and statistics configuration
and buffer output (all very similar to how rkisp1 does this, which I have quite
a bit of experience with) + missing formats that thw HW supports.

So I'm pretty far into the whole re-debug on device process on this driver. :)

It would be nice if this series landed so I can submit my work without conflicts.
And I'm also sending this mail so that people know there's someone working on
this driver, to not duplicate work.

And it would be nice once I submit it if someone with bayer output sensor would
do the tests on ISP blocks that work with that (which are also part of my work
but will be untested).

Best regards,
	o.j.
