This patch adds a generic w1 bindings document that describes how w1 slave deviceses are grouped under master nodes. It also augments the existing w1-gpio.txt document a bit.

Generic devicetree bindings for onewire (w1) busses
|
|
===================================================
|
|
|
|
Onewire busses are described through nodes of their master bus controller.
|
|
Slave devices are listed as sub-nodes of such master devices. For now, only
|
|
one slave is allowed per bus master.
|
|
|
|
|
|
Example:
|
|
|
|
charger: charger {
|
|
compatible = "gpio-charger";
|
|
charger-type = "mains";
|
|
gpios = <&gpio 1 GPIO_ACTIVE_LOW>;
|
|
};
|
|
|
|
onewire {
|
|
compatible = "w1-gpio";
|
|
gpios = <&gpio 100 0>, <&gpio 101 0>;
|
|
|
|
battery {
|
|
compatible = "maxim,ds2760";
|
|
power-supplies = <&charger>;
|
|
};
|
|
};
