Device tree bindings? -


do have go through device tree bindings documentation of linux kernel when start working on it.
there no standard set of fields in device tree followed distros/kernel sources?

secondly need guidance regarding adding nodes devices on gpio bus using device tree. have consulted http://devicetree.org/device_tree_usage.

stackoverflow-query here should point documentation on device tree. , yes idea go through documentation before dive using it.

as gpio devices (i assume have gpio controller in place in dts/dtsi file in place), there should plenty under arch/arc/boot/dts . pick 1 :)!

eg: gpio1_8 mmc dts , gpio1 controller dtsi
