|
||||||
|
|
||||||
|
Android goldfish tty device generated by android emulator.
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
|
||||||
|
- compatible : should contain "google,goldfish-tty" to match emulator
|
||||||
|
- reg : <registers mapping>
|
||||||
|
- interrupts : <interrupt mapping>
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
goldfish_tty@1f004000 {
|
||||||
|
compatible = "google,goldfish-tty";
|
||||||

reg = <0x1f004000 0x1000>;
|
||||||
|
interrupts = <0xc>;
