* 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>;
|
|
};
