 *
 * Driver for Si5351A chip.
 * VFO 0 is a quadrature clock on outputs 0 and 1, 
 * VFO 1 is a regular clock on output 2.
 *
 * The quadrature clock allows to set shared frequency and phase offsets of 0, 90, 180 and 270 deg
 * The regular clock just allows to set frequency, phase is ignored
 * 
 * See si5351.c for more information
