* 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>;
};
