Set SPI baudrate.

int32_t spi_m_async_set_baudrate(
    struct spi_m_async_descriptor * spi,
    const uint32_t baud_val
)

Works if the SPI is initialized as master. In the function a sanity check is used to confirm it's called in the correct mode.

baud_val

Type: const uint32_t

The target baudrate value (see "baudrate calculation" for calculating the value).
