So I had a poke at the ov9282 today.

ov9282 is detected on this branch here.

https://git.linaro.org/people/bryan.odonoghue/kernel.git/log/?h=linux-stable-22-08-01-imx577-camss

libcamera can't eat Y10P though

Ongoing irritant is that i2c addresses are right shifted by 1 bit in 
addressing so imx577@x34 is imx577@0x1a and ov9282@0xC0 is ov9282@0x60, 
we should fix that, its very confusing.

Anyway I thought I'd share
