That would be great !

Not to my knowledge. I'm not (at least for now, but I could need H3A support
at some point in the future).

The AF and AE engines look pretty similar indeed. It would be nice if the
OMAP3 ISP AF and AE code could be shared with the OMAP4 ISS driver. That would
require some refactoring though. One thing we're missing is standardization of
H3A APIs in V4L2, I'd like to see that happen.

Here's the full pipeline configuration I use. Please note that the OMAP4 ISS
resizer implementation doesn't support resizing yet, it just hardcodes the
resizer ratio to 1:1.
IFMT="SBGGR10"
ISIZE="1920x1084"
OFMT="UYVY"
OSIZE="1920x1080"
CFMT="YUYV1_5X8"
media-ctl -l '"OMAP4 ISS CSI2a":1 -> "OMAP4 ISS ISP IPIPEIF":0 [1]'
media-ctl -l '"OMAP4 ISS ISP IPIPEIF":2 -> "OMAP4 ISS ISP IPIPE":0 [1]'
media-ctl -l '"OMAP4 ISS ISP IPIPE":1 -> "OMAP4 ISS ISP resizer":0 [1]'
media-ctl -l '"OMAP4 ISS ISP resizer":1 -> "OMAP4 ISS ISP resizer a output":0
[1]'
media-ctl -V "\"sensor\":0 [fmt:$IFMT/$ISIZE]"
media-ctl -V "\"OMAP4 ISS CSI2a\":1 [fmt:$IFMT/$ISIZE]"
media-ctl -V "\"OMAP4 ISS ISP IPIPEIF\":0 [fmt:$IFMT/$ISIZE]"
media-ctl -V "\"OMAP4 ISS ISP IPIPE\":0 [fmt:$IFMT/$ISIZE]"
media-ctl -V "\"OMAP4 ISS ISP IPIPE\":1 [fmt:$OFMT/$OSIZE]"
media-ctl -V "\"OMAP4 ISS ISP resizer\":0 [fmt:$OFMT/$OSIZE]"
media-ctl -V "\"OMAP4 ISS ISP resizer\":1 [fmt:$CFMT/$OSIZE]"
