|
+W1 gpio device binding - one wire protocol over bitbanged gpio
|
|
|
+=======================
|
|
|
+
|
|
|
+
|
|
|
+Child nodes are required in device tree. The driver will detect
|
|
|
+the devices serial number and then search in the child nodes in the device tree
|
|
|
+for the proper node and try to match it with the device.
|
|
|
+
|
|
|
+Also check doc/device-tree-bindings/w1-eeprom for possible child nodes drivers
|
|
|
+
|
|
|
+Driver:
|
|
|
+- drivers/w1/w1-gpio.c
|
|
|
+
|
|
|
+Software w1 device-tree node properties:
|
|
|
+Required:
|
|
|
+* compatible = "w1-gpio";
|
|
|
+* gpios = <...>;
|
|
|
+ This is the gpio used for one wire protocol, using bitbanging
|
|
|
+
|
|
|
+Optional:
|
|
|
+* none
|
|
|
+
|
|
|
+Example:
|
|
|
+
|
|
|
+onewire_tm: onewire {
|
|
|
+ compatible = "w1-gpio";
|
|
|
+ gpios = <&pioA 32 0>;
|
|
|
+};
|
|
|
+
|
|
|
+Example with child:
|
|
|
+
|
|
|
+onewire_tm: onewire {
|
|
|
+ compatible = "w1-gpio";
|
|
|
+ gpios = <&pioA 32 0>;
|
|
|
+
|
|
|
+ eeprom1: eeprom@0 {
|
|
|
+ compatible = "maxim,ds24xxx";
|
|
|
+ }
|
|
|
+};
