  30  * A chip is described by a set of unique devices.

  32  * Each sub-arch has its own master list of unique devices and
  33  * enumerates them by enum fsl_devices in a sub-arch specific header
  34  *
  35  * The platform data structure is broken into two parts.  The
  36  * first is device specific information that help identify any
  37  * unique features of a peripheral.  The second is any
  38  * information that may be defined by the board or how the device
  39  * is connected externally of the chip.
  40  *
  41  * naming conventions:
  42  * - platform data structures: <driver>_platform_data
  43  * - platform data device flags: FSL_<driver>_DEV_<FLAG>
  44  * - platform data board flags: FSL_<driver>_BRD_<FLAG>
