* 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>; |
|
};
