25 * unique device: a platform_device entry in fsl_plat_devs[] plus
26 * associated device information in its platform_data structure.
27 *
28 * A chip is described by a set of unique devices.
29 *
30 * Each sub-arch has its own master list of unique devices and
31 * enumerates them by enum fsl_devices in a sub-arch specific header
32 *
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
41 * - platform data device flags: FSL_<driver>_DEV_<FLAG>
42 * - platform data board flags: FSL_<driver>_BRD_<FLAG>
