3A device which handles data aquisition from compatible USB based peripherals.
4SPI is used for device management.
5
6Note: This device does not expose the peripherals as USB devices.

8Required properties:
9
10- compatible : Should be "ge,achc"
11
12Required SPI properties:
13
14- reg : Should be address of the device chip select within
15 the controller.
16
17- spi-max-frequency : Maximum SPI clocking speed of device in Hz, should be
18 1MHz for the GE ACHC.

20Example:
21
22spidev0: spi@0 {
23 compatible = "ge,achc";
24 reg = <0>;
25 spi-max-frequency = <1000000>;
26};
