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. | |
