* Common file for GPMC connected smsc9221 on omaps

*
|
||
|
|
* Compared to smsc911x, smsc9221 (and others like smsc9217
|
||
|
|
* or smsc 9218) has faster timings, leading to higher
|
||
|
|
* bandwidth.
|
||
|
|
*
|
||
|
|
* Note that the board specifc DTS file needs to specify
|
||
|
|
* ranges, pinctrl, reg, interrupt parent and interrupts.
