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.
