You're sending an arbitrary 4 bytes of a 64-bit value. This works on little
endian
but will not on big endian.
Please properly copy this clkrate into a "u32" variable and pass that into
sja1105_spi_send_int().
It also seems to suggest that you want to use abs() to perform that weird
centering around 1 << 31 calculation.
Thank you.
