[PATCH 1/5] wifi: ath11k: rearrange IRQ enable/disable in reset path

[Baochen Qiang]

For non WoW suspend/resume, ath11k host powers down whole hardware
when suspend and powers up it when resume, the code path it goes
through is very like the ath11k reset logic.

In order to reuse that logic, rearrange IRQ handling in the reset
path.

[PATCH 2/5] wifi: ath11k: remove MHI LOOPBACK channels

[Baochen Qiang]

There is no driver to match these two channels, so
remove them. This fixes warnings from MHI subsystem during suspend:

mhi mhi0_LOOPBACK: 1: Failed to reset channel, still resetting
mhi mhi0_LOOPBACK: 0: Failed to reset channel, still resetting

[PATCH 3/5] wifi: ath11k: do not dump SRNG statistics during resume

[Baochen Qiang]

Both the firmware reset feature and the power management
suspend/resume feature share common power-down and power-up
functionality. One aspect of the power-up functionality is
the handling of the ATH11K_QMI_EVENT_FW_INIT_DONE event.
When this event is received, a call is made to
ath11k_hal_dump_srng_stats(), with the purpose to collect
information that may be useful in debugging the cause of a
firmware reset.

Unfortunately, since this functionality is shared between
both the firmware reset path and the power management
resume path, the kernel log is flooded with messages during
resume. Since these messages are not useful during resume,
and in fact can be confusing and can increase the time it
takes to resume, update the logic to only call
ath11k_hal_dump_srng_stats() during firmware reset.

[PATCH 4/5] wifi: ath11k: fix warning on DMA ring capabilities event

[Baochen Qiang]

We are seeing below warning in both reset and suspend/resume scenarios:

[69663.691847] ath11k_pci 0000:02:00.0: Already processed, so ignoring dma ring caps

This is because ab->num_db_cap is not cleared in
ath11k_wmi_free_dbring_caps(), so clear it to avoid such
warnings.

[PATCH 5/5] wifi: ath11k: thermal: don't try to register multiple times

[Baochen Qiang]

From: Kalle Valo <quic_kvalo@quicinc.com>

Every time the firmware boots we call ath11k_core_qmi_firmware_ready() which
ends up calling ath11k_thermal_register(). So we try to register thermal
devices multiple times. And when we power off the firmware during
suspend/hibernation (implemented in the next patch) we get a warning in resume:

hwmon hwmon4: PM: parent phy0 should not be sleeping

Workaround this similarly like ath11k_mac_register() does by testing
ATH11K_FLAG_REGISTERED.

Oh, sorry for missing that.

Hi Kalle, I see you have put this series in pending branch. I am

I can add it in the pending branch if you send it to me as a reply to
this mail. s-o-b is like a signature so I won't add it on my own.
