Adding dallas 1-wire over GPIO support
I need to enable 1-wire bus support on arch linux arm. I have rebuilt the kernel with 1-wire support enabled and the 1-wire bus master gpio support enabled as a kernel module.
When I load the w1-gpio kernel module , it fails with
device not found
so clearly I have not defined the gpio device for the w1-gpio kernel module to use as the 1wire bus master.
Does anyone know how to define the gpio for use by the native kernel support for dallas 1-wire devices?
The kernel is 3.7.x and the SBC is the olimex maxi.
