29 * unique device: a platform_device entry in fsl_plat_devs[] plus
30 * associated device information in its platform_data structure.
31 *
32 * A chip is described by a set of unique devices.
33 *
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.
42 *
43 * naming conventions:
44 * - platform data structures: <driver>_platform_data
45 * - platform data device flags: FSL_<driver>_DEV_<FLAG>
46 * - platform data board flags: FSL_<driver>_BRD_<FLAG>
