ath9k: make relay callbacks const

2020-12-16T06:46:18+00:00

Now that relay_open() accepts const callbacks, make relay callbacks
const.

Merge ath-next from git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git

2020-12-12T04:51:34+00:00

ath.git patches for v5.11. Major changes:

ath11k

* suspend support for QCA6390 PCI devices

* support TXOP duration based RTS threshold

* mesh: add support for 256 bitmap in blockack frames in 11ax

ath11k: implement suspend for QCA6390 PCI devices

2020-12-12T04:41:44+00:00

Now that all the needed pieces are in place implement suspend support QCA6390
PCI devices. All other devices will return -EOPNOTSUPP during suspend. The
suspend is implemented by switching the firmware to WoW mode during suspend, so
the firmware will be running on low power mode while host is in suspend.

At the moment we are not able to shutdown and fully power off the device due to
bugs in MHI subsystem, so WoW mode is a workaround for the time being.

During suspend we enable WoW mode, disable CE irq and DP irq, then put MHI to
suspend state.  During resume, driver resumes MHI firstly, then enables CE irq
and dp IRQ, and sends WoW wakeup command to firmware.

ath11k: hif: add ce irq enable and disable functions

2020-12-12T04:41:41+00:00

Add ce irq enable and disable hif layer functions, so core module can enable
enable them without cleaning pipe and refilling pipe. Needed for suspend.

ath11k: set credit_update flag for flow controlled ep only

2020-12-12T04:41:34+00:00

Firmware will check all the pipes before entering WoW mode during suspend. If
ATH11K_HTC_FLAG_NEED_CREDIT_UPDATE is set, firmware treats this pipe needed to
return credit even though it's actually not required. If any pipe needs to
return credit, the suspend_complete message doesn't send to host but is
dropped.  So host gets time out and WoW suspend failed.

ath11k: dp: stop rx pktlog before suspend

2020-12-12T04:41:31+00:00

Stop dp rx pktlog when entering suspend and reap the mon_status buffer to keep
it empty. During resume restart the reap timer.

ath11k: htc: implement suspend handling

2020-12-12T04:41:28+00:00

When ath11k sends suspend command to firmware, firmware will
return suspend_complete events and add handlers for those.
