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