Same is the case with non-WoW suspend, chip will not be put into low power mode when the system is suspended resulting in higher battery drain. Send QMI MODE OFF command to firmware during WiFi OFF to put device into low power mode.

A future patch will be sent to enable the logic for other devices. - Rebased on ToT drivers/net/wireless/ath/ath11k/ahb.c | 45 +++++ drivers/net/wireless/ath/ath11k/core.c | 229 ++++++++++++++++++------- drivers/net/wireless/ath/ath11k/core.h | 8 +- drivers/net/wireless/ath/ath11k/hal.c | 1 + drivers/net/wireless/ath/ath11k/hif.h | 12 ++ drivers/net/wireless/ath/ath11k/mac.c | 33 ++-- drivers/net/wireless/ath/ath11k/pci.c | 26 +++ drivers/net/wireless/ath/ath11k/reg.c | 2 + 8 files changed, 264 insertions(+), 92 deletions(-)
