[RESEND v2] dmaengine: pxa: add a default requestor policy

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

 



As what former drcmr -1 value meant, add a this as a default to each
channel, ie. that by default no requestor line is used.

This is specifically used for network drivers smc91x and smc911x, and
needed for their port to slave maps.
