  31 * Some conventions on how we handle peripherals on Freescale chips
  32 *
  33 * unique device: a platform_device entry in fsl_plat_devs[] plus
  34 * associated device information in its platform_data structure.
  35 *
  36 * A chip is described by a set of unique devices.
  37 *
  38 * Each sub-arch has its own master list of unique devices and
  39 * enumerates them by enum fsl_devices in a sub-arch specific header
  40 *
  41 * The platform data structure is broken into two parts.  The
  42 * first is device specific information that help identify any
  43 * unique features of a peripheral.  The second is any
  44 * information that may be defined by the board or how the device
  45 * is connected externally of the chip.
  46 *
  47 * naming conventions:
  48 * - platform data structures: <driver>_platform_data
  49 * - platform data device flags: FSL_<driver>_DEV_<FLAG>
  50 * - platform data board flags: FSL_<driver>_BRD_<FLAG>
