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@0 {
|
|
compatible = "maxim,ds24xxx";
|
|
}
|
|
|
|
Example with parent bus:
|
|
|
|
onewire_tm: onewire {
|
|
compatible = "w1-gpio";
|
|
gpios = <&pioA 32 0>;
|
|
|
|
eeprom1: eeprom@0 {
|
|
compatible = "maxim,ds24xxx";
|
|
}
|
|
};
