Linux/BEAGLEBK: 1-wire access / what entry is required in arch/arm/boot/dts/am335x-boneblack.dtb

Part Number:BEAGLEBK

Tool/software: Linux

Hello,

I'm able to configure / compile / install / boot kernel and modules for 1-wire support.

Have Dallas DS18B20 temp sensors.

modprobe w1_therm       ok

lsmod
Module                  Size  Used by
w1_therm                5618  0
wire                   23592  1 w1_therm

But what exactly do I have to add to arch/arm/boot/dts/am335x-boneblack.dts?

Temp sensors are connected on P9_12    .... expect that's currently unknown for w1_therm

Thanks for help
