31 * Some conventions on how we handle peripherals on Freescale chips
33 * unique device: a platform_device entry in fsl_plat_devs[] plus
34 * associated device information in its platform_data structure.
36 * A chip is described by a set of unique devices.
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
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.
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>
