From 4a3c212eee0e36c1cd55bfbfb94041a0d3ad265b Mon Sep 17 00:00:00 2001 From: Baochen Qiang Date: Wed, 19 Jun 2024 17:21:11 +0300 Subject: wifi: ath12k: add basic WoW functionalities Implement basic WoW functionalities such as magic-packet, disconnect and pattern. The logic is very similar to ath11k. When WoW is configured, ath12k_core_suspend and ath12k_core_resume are skipped (by checking ar->state) as we are not allowed to power cycle firmware.
