What combination of RPI model, kernel (and dtb files) you try to use ?

I'm using -current NetBSD 9.99.46 (GENERIC) figuring it probably has the latest & greatest.

Raspberry Pi 3 Model B Plus Rev 1.3 - so I'm not sure which of the highlighted dtb files is used.

# cd /boot

# ls -l *dtb
-rwxr-xr-x 1 root wheel 27054 Dec 22 12:30 bcm2710-rpi-3-b-plus.dtb*

Raspberry Pi 3 Model B Plus Rev 1.3 - so I'm not sure which of the highlighted dtb files is used.

I've attached the 'strings' output of those two dtb files. They both seem to have i2c* entries.

Thanks for all help.

netbsd-9 has it defined in GENERIC and the dtb files we deliver have
configured the i2c ports.

netbsd-8 doesn't have a GENERIC kernel, you use the RPI kernel which
also defines the iic interfaces.

What combination of RPI model, kernel (and dtb files) you try to use ?
