This driver supports the SPI controller on the MPC83xx SoC devices from Freescale. Note, this driver supports only the simple shift register SPI controller and not the descriptor based CPM or QUICCEngine SPI controller.

* A chip is described by a set of unique devices.

|
|
* 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>
