Those patch series make cameras on Nokia N900 partially working.
Some more patches are needed, but I've already sent them for
upstreaming so they are not part of the series:
https://lkml.org/lkml/2016/4/16/14
https://lkml.org/lkml/2016/4/16/33
As omap3isp driver supports only one endpoint on ccp2 interface,
but cameras on N900 require different strobe settings, so far
it is not possible to have both cameras correctly working with
the same board DTS. DTS patch in the series has the correct
settings for the front camera. This is a problem still to be
solved.
The needed pipeline could be made with:
media-ctl -r
media-ctl -l '"vs6555 binner 2-0010":1 -> "video-bus-switch":2 [1]'
media-ctl -l '"video-bus-switch":0 -> "OMAP3 ISP CCP2":0 [1]'
media-ctl -l '"OMAP3 ISP CCP2":1 -> "OMAP3 ISP CCDC":0 [1]'
media-ctl -l '"OMAP3 ISP CCDC":2 -> "OMAP3 ISP preview":0 [1]'
media-ctl -l '"OMAP3 ISP preview":1 -> "OMAP3 ISP resizer":0 [1]'
media-ctl -l '"OMAP3 ISP resizer":1 -> "OMAP3 ISP resizer output":0 [1]'
media-ctl -V '"vs6555 pixel array 2-0010":0 [SGRBG10/648x488 (0,0)/648x488 (0,0)/648x488]'
media-ctl -V '"vs6555 binner 2-0010":1 [SGRBG10/648x488 (0,0)/648x488 (0,0)/648x488]'
media-ctl -V '"OMAP3 ISP CCP2":0 [SGRBG10 648x488]'
media-ctl -V '"OMAP3 ISP CCP2":1 [SGRBG10 648x488]'
media-ctl -V '"OMAP3 ISP CCDC":2 [SGRBG10 648x488]'
media-ctl -V '"OMAP3 ISP preview":1 [UYVY 648x488]'
media-ctl -V '"OMAP3 ISP resizer":1 [UYVY 656x488]'
and tested with:
mplayer -tv driver=v4l2:width=656:height=488:outfmt=uyvy:device=/dev/video6 -vo xv -vf screenshot tv://
4.6-rc4 + twl regulator patch + the patches mentioned above + this
patchset (I put everything together here [0]) do _not_ work for me.
The error matches what I have seen when I was working on it: No
image data seems to be received by the ISP. For example there are
no related IRQs:
root@n900:~# cat /proc/interrupts | grep ISP
40: 0 INTC 24 Edge 480bd400.mmu, OMAP3 ISP
I tested with mpv and yavta (yavta --capture=8 --pause --skip 0
--format UYVY --size 656x488 /dev/video6)
[0] https://git.kernel.org/cgit/linux/kernel/git/sre/linux-n900.git/log/?h=n900-camera-ivo
Ok, going to diff with my tree to see what I have missed to send in the
patchset
Thanks
