+Maxim DS24 families driver device binding - one wire protocol EEPROMS from Maxim
+=======================
+
+This memory needs to be connected to a onewire bus, as a child node.
+The bus will read the device serial number and match this node with a found
+device on the bus
+Also check doc/device-tree-bindings/w1 for onewire bus drivers
+
+Driver:
+- drivers/w1-eeprom/ds24xxx.c
+
+Software ds24xxx device-tree node properties:
+Required:
+* compatible = "maxim,ds24b33"
+or
+* compatible = "maxim,ds2431"
+Further memories can be added.
+
+Optional:
+* none
+
+Example:
+ eeprom1: eeprom at 0 {
+ compatible = "maxim,ds24xxx";
+ }
+
+Example with parent bus:
+
+onewire_tm: onewire {
+ compatible = "w1-gpio";
+ gpios = <&pioA 32 0>;
+
+ eeprom1: eeprom at 0 {
+ compatible = "maxim,ds24xxx";
+ }
+};
