1-wire on Udoo (imx6qdl)

I'm trying to get 1-wire implemented on a Udoo Quad (i.mx6qdl), and have been searching through various examples on how to do it (Raspberry Pi/BeagleBone etc).  I added in kernel support for w1-gpio and w1-therm, but I'm not sure what syntax needs to be added into the device tree (linux_kernel/imx6qdl-udoo.dtsi at imx_3.14.28_1.0.0_ga_udoo · UDOOboard/linux_kernel · GitHub ).

 

I looked at the beaglebone implementation (BeagleBone Black 1-Wire Temperature with Debian 8 (Jessie), Kernel 4.1.x and No Capemgr ) and someone pointed me to a SAM9x5 implementation (arch/arm/boot/dts/at91sam9x5cm.dtsi - kernel/common.git - Git at Google ), but I'm still a bit confused (I'm new to kernels).

 

Any ideas?

 

Thanks!

Pete
