OK sorry I thought you were referring to config pin on I2C.

I2C uses clock stretching but I'm not aware of any SPI interfaces that do it.
However, it may be that the hardware is shared.

It's probably for clock-stretching. Both pins clock and data need to go both

Thanks - you saved my day! I just ran into the same quirk. Truly bizzare that
the SPI_CLK pinmux has to be set as an input in master mode where the pin is
clearly an output.

Ok at least I'm not that stupid then. ;)

Its a quirk of the SPI hardware as far as I can tell, even on the original
Beagleboard the SPI_CLK pinmux has to be set as an input.
