+Android Goldfish framebuffer
+
+Android Goldfish framebuffer device used by Android emulator.
+
+Required properties:
+
+- compatible : should contain "google,goldfish-fb"
+- reg : <registers mapping>
+- interrupts : <interrupt mapping>
+
+Example:
+
+ display-controller@1f008000 {
+ compatible = "google,goldfish-fb";
+ interrupts = <0x10>;
+ reg = <0x1f008000 0x100>;
+ };
This is the frame buffer device driver for the SBUS-based Sun ZX
(leo) frame buffer cards.

- Despite of IGA Card has advanced graphic acceleration,
