      1* Liebherr's BK4 controller external SPI
      2
      3A device which handles data acquisition from compatible industrial
      4peripherals.
      5The SPI is used for data and management purposes in both master and
      6slave modes.
      7
      8Required properties:
      9
     10- compatible : Should be "lwn,bk4"
     11
     12Required SPI properties:
     13
     14- reg : Should be address of the device chip select within
     15  the controller.
     16
     17- spi-max-frequency : Maximum SPI clocking speed of device in Hz, should be
     18  30MHz at most for the Liebherr's BK4 external bus.

     20Example:
     21
     22spidev0: spi@0 {
     23	compatible = "lwn,bk4";
     24	spi-max-frequency = <30000000>;
     25	reg = <0>;
     26};
