| * device tree support addition for the S3C2416 architecture. |
| * |
| * 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. |
