| audclk |
| Specific to the P1022DS reference board. |
| |
| This option specifies which of the two oscillator frequencies should be |
| routed to the Wolfson WM8776 codec. The ngPIXIS can be programmed to |
| route either a 11.2896MHz or a 12.288MHz clock. The default is |
| 12.288MHz. This option has two effects. First, the MUX on the board |
| will be programmed accordingly. Second, the clock-frequency property |
| in the codec node in the device tree will be updated to the correct |
| value. |
| |
| 'audclk:11' |
| Select the 11.2896MHz clock |
| |
| 'audclk:12' |
| Select the 12.288MHz clock |
