[PATCH 1/2] ath10k: Make CE layer bus agnostic
Govind Singh
govinds at qti.qualcomm.com
Tue Jun 27 21:48:26 PDT 2017
Remove bus specific dependencies from CE layer
to have common CE layer across multiple targets.
This is required for adding support for WCN3990
chipset support as WCN3990 chipset uses SNOC
bus interface with Copy Engine endpoint.
