24 * Some conventions on how we handle peripherals on Freescale chips
26 * unique device: a platform_device entry in fsl_plat_devs[] plus
27 * associated device information in its platform_data structure.
29 * A chip is described by a set of unique devices.
31 * Each sub-arch has its own master list of unique devices and
32 * enumerates them by enum fsl_devices in a sub-arch specific header
34 * The platform data structure is broken into two parts. The
35 * first is device specific information that help identify any
36 * unique features of a peripheral. The second is any
37 * information that may be defined by the board or how the device
38 * is connected externally of the chip.
