1OpenCores tiny SPI 2 3Required properties: 4- compatible : should be "opencores,tiny-spi-rtlsvn2". 5- gpios : should specify GPIOs used for chipselect. 6Optional properties: 7- clock-frequency : input clock frequency to the core. 8- baud-width: width, in bits, of the programmable divider used to scale 9 the input clock to SCLK. 10 11The clock-frequency and baud-width properties are needed only if the divider 12is programmable. They are not needed if the divider is fixed. 13
