1 | Freescale-specific 'hwconfig' options. |

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

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. | |
