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
