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

  
  usb
  	Specific to boards have USB controller
  
  	This option specifies the following for a USB controller:
  
  		- which controller mode to use
  		- which USB PHY to use
  
  	This is used by generic USB device-tree fixup function to update
  	modified values of phy type and controller mode.
  
  	Also used for configuring multiple USB controllers such that
  	'usbN' (where N is 1, 2, etc. refers to controller no.)
  
  	'phy_type'
  		Select USB phy type: 'utmi' OR 'ulpi'
  
  	'dr_mode'
  		Select USB controller mode: 'host', 'peripheral' OR 'otg'
  
  	Examples:
  		usb1:dr_mode=host;usb2:dr_mode=peripheral'
  
  		usb1:dr_mode=host,phy_type=utmi;usb2:dr_mode=host'
