|
|
- compatible: must be "selftest"
|
|
|
|
All other properties are optional.
|
|
|
|
Example:

status = "okay";
|
|
};
|
|
|
|
2) OF selftest i2c adapter platform device
|
|
|
|
** platform device unittest adapter
|
|
|
|
Required properties:
|
|
- compatible: must be selftest-i2c-bus
|
|
|
|
Children nodes contain selftest i2c devices.
|
|
|
|
Example:
|
|
selftest-i2c-bus {
|
|
compatible = "selftest-i2c-bus";
|
|
status = "okay";
|
|
};
|
|
|

|
|
selftest-i2c-mux {
|
|
compatible = "selftest-i2c-mux";
|
|
status = "okay";
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
channel-0 {
|
|
reg = <0>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
