| * 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>;
| };
