| 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. |
