|
|
*
|
|
* For drivers that require platform data to be provided from the machine
|
|
* file, a platform data pointer can also be supplied along with the
|
|
* devices names. Usually, the platform data elements that cannot be parsed
|
|
* from the device tree by the drivers (example: function pointers) are
|
|
* supplied. But it should be noted that this is a temporary mechanism and
|
|
* at some point, the drivers should be capable of parsing all the platform
|
|
* data from the device tree.
