+* GE Healthcare USB Management Controller
+
+A device which handles data aquisition from compatible USB based peripherals.
+SPI is used for device management.
+
+Note: This device does not expose the peripherals as USB devices.
+
+Required properties:
+
+- compatible : Should be "ge,achc"
+
+Required SPI properties:
+
+- reg : Should be address of the device chip select within
+ the controller.
+
+- spi-max-frequency : Maximum SPI clocking speed of device in Hz, should be
+ 1MHz for the GE ACHC.
+
+Example:
+
+spidev0: spi@0 {
+ compatible = "ge,achc";
+ reg = <0>;
+ spi-max-frequency = <1000000>;
+};
