spi_hal_cal_timing() function

Clock freq of selected clock source for SPI in Hz.

Actual SPI clock frequency

true if the GPIO matrix is used, otherwise false.

Maximum delay between SPI launch clock and the data to be valid. This is used to compensate/calculate the maximum frequency allowed. Left 0 if not known.

Dummy cycles required to correctly read the data.

suggested delay on the MISO line, in APB clocks.
