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

34  * Each sub-arch has its own master list of unique devices and
35  * enumerates them by enum fsl_devices in a sub-arch specific header
36  *
37  * The platform data structure is broken into two parts.  The
38  * first is device specific information that help identify any
39  * unique features of a peripheral.  The second is any
40  * information that may be defined by the board or how the device
41  * is connected externally of the chip.

43  * naming conventions:
44  * - platform data structures: <driver>_platform_data
45  * - platform data device flags: FSL_<driver>_DEV_<FLAG>
