29 * The following lookup table is used to override device names when devices
30 * are registered from device tree. This is temporarily added to enable
31 * device tree support addition for the EXYNOS5 architecture.
32 *
33 * For drivers that require platform data to be provided from the machine
34 * file, a platform data pointer can also be supplied along with the
35 * devices names. Usually, the platform data elements that cannot be parsed
36 * from the device tree by the drivers (example: function pointers) are
37 * supplied. But it should be noted that this is a temporary mechanism and
38 * at some point, the drivers should be capable of parsing all the platform
39 * data from the device tree.
