* 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>;
};
