| 3 | This file documents Freescale-specific key:value pairs for the 'hwconfig' |
| 4 | option. See README.hwconfig for general information about 'hwconfig'. |

| 6 | audclk |
| 7 | Specific to the P1022DS reference board. |

| 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. |
