WLAN firmware uses SMP2P protocol in order to talk to the application processor (AP) in certain cases like WoW (Wake on Wireless). WLAN firmware runs on the WPSS Q6 processor (Wireless Processor SubSystem). Therefore it is required to have sub nodes pertaining to the WPSS Q6 processor and the application processor in the SMP2P node. Add WPSS Q6 (Wireless Processor SubSystem) node names to the pattern property required for WPSS Q6 processor to communicate to the application processor and vice versa over SMP2P protocol.
