It is a RPi3 board. The exact procedure that I took is described here:
https://blogs.s-osg.org/use-v4l2-cameras-raspberry-pi-3-upstream-kernel/
After it, I updated the firmware to the newest one, from:
https://github.com/raspberrypi/firmware.git
commit 384559354762f36aa55584560d8749fc66a4cfd0
Author: popcornmix <popcornmix@...il.com>
Date: Sat Mar 18 17:48:59 2017 +0000
kernel: Bump to 4.9.16
Then I applied two patches on the top of it:
https://patchwork.linuxtv.org/patch/40093/
https://patchwork.linuxtv.org/patch/40146/
As the second patch has entries for vchiq, I ended by having it
duplicated (although the DTB has it only once, as you can see below).
Regards,
Mauro
