| * 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>; |
| }; |
