2 * Common file for GPMC connected smsc9221 on omaps
3 *
4 * Compared to smsc911x, smsc9221 (and others like smsc9217
5 * or smsc 9218) has faster timings, leading to higher
6 * bandwidth.
7 *
8 * Note that the board specifc DTS file needs to specify
9 * ranges, pinctrl, reg, interrupt parent and interrupts.
