Kernel-4.18.0-80.el8_spi_oc_tiny

OpenCores tiny SPI

Required properties:

  • compatible : should be “opencores,tiny-spi-rtlsvn2”.
  • gpios : should specify GPIOs used for chipselect.
    Optional properties:
  • clock-frequency : input clock frequency to the core.
  • baud-width: width, in bits, of the programmable divider used to scale
    the input clock to SCLK.

The clock-frequency and baud-width properties are needed only if the divider
is programmable. They are not needed if the divider is fixed.
