24 | * Some conventions on how we handle peripherals on Freescale chips | |
25 | * | |
26 | * unique device: a platform_device entry in fsl_plat_devs[] plus | |
27 | * associated device information in its platform_data structure. | |
28 | * | |
29 | * A chip is described by a set of unique devices. | |
30 | * | |
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 | |
33 | * | |
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. | |
39 | * | |
40 | * naming conventions: | |
41 | * - platform data structures: <driver>_platform_data | |
42 | * - platform data device flags: FSL_<driver>_DEV_<FLAG> | |
43 | * - platform data board flags: FSL_<driver>_BRD_<FLAG> | |
