2020-12-12ath11k: implement suspend for QCA6390 PCI devicesCarl Huang
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.

2020-12-12ath11k: set credit_update flag for flow controlled ep onlyCarl Huang
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.

Just when resume from WoW, the write to select_window doesn't take effect immediately, so read the register again to ensure the write operation is finished. Another change is to reset select_window to ZERO because this register isn't restored after WoW, so the content of this register becomes ZERO too.

2020-12-12ath10k: add atomic protection for device recoveryWen Gong
When it has more than one restart_work queued meanwhile, the 2nd restart_work is very easy to break the 1st restart work and lead recovery fail. Add a flag to allow only one restart work running untill device successfully recovered. It already has flag ATH10K_FLAG_CRASH_FLUSH, but it can not use this flag again, because it is clear in ath10k_core_start. The function ieee80211_reconfig(called by ieee80211_restart_work) of mac80211 do many things and drv_start(call to ath10k_core_start) is 1st thing, when drv_start complete, it does not mean restart complete. So it add new flag and clear it in ath10k_reconfig_complete, because it is the last thing called from drv_reconfig_complete of function ieee80211_reconfig, after it, the restart process finished.

In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning by replacing a /* fall through */ comment with the new pseudo-keyword macro fallthrough; instead of letting the code fall through to the next case. Notice that Clang doesn't recognize /* fall through */ comments as implicit fall-through markings. Link: https://github.com/KSPP/linux/issues/115 Signed-off-by: Gustavo A. R.

2020-12-10iwlwifi: support firmware reset handshakeJohannes Berg
There are some races in the hardware that can possibly lead to a bus lockup later during a restart when we manage to kill the firmware at a bad time (while it's accessing the bus). To work around this, add support for a new handshake between firmware and driver to ensure that the firmware is in a well- known state before we kill it.

2020-12-10iwlwifi: mvm: fix a race in CSA that caused assert 0x3420Sara Sharon
When we get a channel switch with a very long quiet period, we schedule a work to disconnect after a while. This work runs in background. In the meanwhile, we keep getting beacons and sending FW modify command for each. This has a potential race, where we modify the CSA after we aborted it. Protect the flow by setting csa_failed to true in case we abort, and check it before sending the modify command. This required a modification to the way we treat csa_failed in iwl_mvm_post_channel_switch: 1. The variable isn't being reset anymore, so we can still look at it in iwl_mvm_channel_switch_rx_beacon. This is fine, since we reset it when starting a new CSA. 2. There is no more early return in case of csa_failed. This is fine, since before this patch csa_failed was set only for GO, and for GO the function is only resetting the power settings, which we want to restore even in case of failure.
