   9         This option specifies which of the two oscillator frequencies should be
  10         routed to the Wolfson WM8776 codec.  The ngPIXIS can be programmed to
  11         route either a 11.2896MHz or a 12.288MHz clock.  The default is
  12         12.288MHz.  This option has two effects.  First, the MUX on the board
  13         will be programmed accordingly.  Second, the clock-frequency property
  14         in the codec node in the device tree will be updated to the correct
  15         value.
