| * 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>;
 | |
| };
