Maxim DS2502 driver device binding - one wire protocol add only memory 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/ds2502.c
|
|
|
|
Ds2502 device-tree node properties:
|
|
Required:
|
|
* compatible = "maxim,ds2502"
|
|
|
|
Optional:
|
|
* none
|
|
|
|
Example:
|
|
eeprom1: eeprom@0 {
|
|
compatible = "maxim,ds2502";
|
|
};
|
|
|
|
Example with parent bus:
|
|
onewire {
|
|
compatible = "fsl,imx53-owire";
|
|
reg = <0x63fa4000 0x4000>;
|
|
|
|
eeprom1: eeprom@0 {
|
|
compatible = "maxim,ds2502";
|
|
};
|
|
};
