1) OF selftest platform device
** selftest
Required properties:
- compatible: must be "selftest"
All other properties are optional.
Example:
selftest {
compatible = "selftest";
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";
};
3) OF selftest i2c device
** I2C selftest device
Required properties:
- compatible: must be selftest-i2c-dev
All other properties are optional
Example:
selftest-i2c-dev {
compatible = "selftest-i2c-dev";
status = "okay";
};
4) OF selftest i2c mux device
** I2C selftest mux
Required properties:
- compatible: must be selftest-i2c-mux
Children nodes contain selftest i2c bus nodes per channel.
Example:
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>;
i2c-dev {
reg = <8>;
compatible = "selftest-i2c-dev";
status = "okay";
};
};
};
