[PATCH 1/3] USB: musb: add reset hook to platform ops

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

 



Babble interrupts require us to reset the DSPS glue layer. In order to
handle all other recovery tasks independently, add a new hook for
platform-specific implementations of the actual reset.
