|
* unique device: a platform_device entry in fsl_plat_devs[] plus
|
|
* associated device information in its platform_data structure.
|
|
*
|
|
* A chip is described by a set of unique devices.
|
|
*
|
|
* Each sub-arch has its own master list of unique devices and
|
|
* enumerates them by enum fsl_devices in a sub-arch specific header
|
|
*
|
|
* The platform data structure is broken into two parts. The
|
|
* first is device specific information that help identify any
|
|
* unique features of a peripheral. The second is any
|
|
* information that may be defined by the board or how the device
|
|
* is connected externally of the chip.
|
|
*
|
|
* naming conventions:
|
|
* - platform data structures: <driver>_platform_data
|
|
* - platform data device flags: FSL_<driver>_DEV_<FLAG>
|
|
* - platform data board flags: FSL_<driver>_BRD_<FLAG>
