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.
