As the Black has a new 3.8.x generation kernel, omap_mux has gone and we're in the realms of using pinctrl for setting up the pins on the expansion headers.
Looking through the bonescript library it appears to try omap_mux and if that fails it just reverts to treating the pin as a gpio. That's all very well until you want to enable a PWM, UART, SPI etc.
So does anyone know what magic is needed on the black ? I'm suffering here from plenty of information on enabling SPI on the original beaglebone with a 3.2.x kernel, but basically zero info on the current state for the Black.
/proc/config.gz says CONFIG_SPI_OMAP24XX=y and I've loaded spi-dev, still no /dev entries for spi and the pinmux settings look wrong. I'm missing something or doing something wrong I'm sure, but right now it seems as if going through /dev/mem, behind pinctrl's back, might be the only way ?
