0001 * Liebherr's BK4 controller external SPI
0002
0003 A device which handles data acquisition from compatible industrial
0004 peripherals.
0005 The SPI is used for data and management purposes in both master and
0006 slave modes.
0007
0008 Required properties:
0009
0010 - compatible : Should be "lwn,bk4"
0011
0012 Required SPI properties:
0013
0014 - reg : Should be address of the device chip select within
0015 the controller.
0016
0017 - spi-max-frequency : Maximum SPI clocking speed of device in Hz, should be
0018 30MHz at most for the Liebherr's BK4 external bus.
0019
0020 Example:
0021
0022 spidev0: spi@0 {
0023 compatible = "lwn,bk4";
0024 spi-max-frequency = <30000000>;
0025 reg = <0>;
0026 };
