[patch-2.6.35 5/8] USB: musb: allow the Blackfin vrsel gpio to be active low

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

 



From: Cliff Cai <cliff.cai@xxxxxxxxxx>

Rather than hardcoding the gpio levels for vrsel, allow the platform
resources to handle this so boards can be active high or low.
