* Liebherr's BK4 controller external SPI
|
|
|
|
A device which handles data acquisition from compatible industrial
|
|
peripherals.
|
|
The SPI is used for data and management purposes in both master and
|
|
slave modes.
|
|
|
|
Required properties:
|
|
|
|
- compatible : Should be "lwn,bk4"
|
|
|
|
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
|
|
30MHz at most for the Liebherr's BK4 external bus.
|
|
|
|
Example:
|
|
|
|
spidev0: spi@0 {
|
|
compatible = "lwn,bk4";
|
|
spi-max-frequency = <30000000>;
|
|
reg = <0>;
|
|
};
