[PATCH 196/220] USB: ehci: omap: use default interrupt threshold

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Anand Gadiyar <gadiyar@xxxxxx>

The current driver reduces the interrupt threshold to 1 microframe.
This was an accidental change and is not really required.
The default of 8 microframes will do just fine. So change it back.
