[TW#12117] HSPI - No clock at 900KHz

[Searaphim]

For some reason when we set 900KHz on the HSPI and send data there is no clock on the HSPI CLK pin. The Chip Select pin does work though. HSPI also works on any other frequency we've tried (below or above 900KHz). It seems a bit odd that this behavior shows up only at that specific clock speed.

To clarify, are you using the driver/spi.h driver and spi_bus_add_device() to configure the HSPI clock? Do you have a snippet of code that demonstrates the bad settings?

Smells like a bug in the clock register calculation code... I'll look into this, working on SPI anyway.
