- 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.
