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

|
|
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
