26 * The following lookup table is used to override device names when devices
27 * are registered from device tree. This is temporarily added to enable
28 * device tree support addition for the Exynos4 architecture.
29 *
30 * For drivers that require platform data to be provided from the machine
31 * file, a platform data pointer can also be supplied along with the
32 * devices names. Usually, the platform data elements that cannot be parsed
33 * from the device tree by the drivers (example: function pointers) are
34 * supplied. But it should be noted that this is a temporary mechanism and
35 * at some point, the drivers should be capable of parsing all the platform
36 * data from the device tree.
