  30  * Each sub-arch has its own master list of unique devices and

  33  * The platform data structure is broken into two parts.  The
  34  * first is device specific information that help identify any
  35  * unique features of a peripheral.  The second is any
  36  * information that may be defined by the board or how the device
  37  * is connected externally of the chip.
  38  *
  39  * naming conventions:
  40  * - platform data structures: <driver>_platform_data
