The current scheme allocates a DMA buffer as big as the requested
firmware package file and DMAs the contents to firmware in one
operation. The buffer size can be several hundred kilo bytes and
the driver may not be able to allocate the memory. This will cause
firmware upgrade to fail.
Improve the scheme by using smaller DMA blocks and calling firmware to
DMA each block in a batch mode. Older firmware can cause excessive
NVRAM erases if the block size is too small so we try to allocate a
256K buffer to begin with and size it down successively if we cannot
allocate the memory.

then loop back and retry one more time.
Since the first try may fail, we use the silent version to send the

On NICs with a smaller NVRAM, FW installation may fail after multiple

The m_can driver's suspend and resume functions (m_can_class_suspend() and
m_can_class_resume()) make use of dev_get_drvdata() and assume that the drvdata
is a pointer to the struct net_device.
With upcoming conversion of the tcan4x5x driver to pm_runtime this assumption
is no longer valid. As the suspend and resume functions actually need a struct
m_can_classdev pointer, change the m_can_platform and the m_can_pci driver to
hold a pointer to struct m_can_classdev instead, as the tcan4x5x driver already
does.

If handling logics of watch events are slower than the events enqueue
logic and the events can be created from the guests, the guests could
trigger memory pressure by intensively inducing the events, because it
will create a huge number of pending events that exhausting the memory.
Fortunately, some watch events could be ignored, depending on its
handler callback. For example, if the callback has interest in only one
single path, the watch wouldn't want multiple pending events. Or, some
watches could ignore events to same path.
To let such watches to volutarily help avoiding the memory pressure
situation, this commit introduces new watch callback, 'will_handle'. If
it is not NULL, it will be called for each new event just before
enqueuing it. Then, if the callback returns false, the event will be
discarded. No watch is using the callback for now, though.

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.

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.

For suspend support add suspend and resume to HIF layer. These ops are optional
and, for example, AHB bus driver does not need to implement these.

Currently 6G specific tlvs have duplicate entries which is causing
scan failures. Fix this by removing the duplicate entries of the same
tlv. This also fixes out-of-bound memory writes caused due to
adding tlvs when num_hint_bssid and num_hint_s_ssid are ZEROs.

For QCA6390, one PCI related clock drifts sometimes, and
it makes PCI link difficult to quit L1ss. Fix it by writing
some registers which are known to fix the problem.

For QCA6390, host needs to reset some registers before MHI power up to fix PCI
link unstable issue if hot reset happened. Also clear all pending interrupts
during power up.

It's recommended to use wmi command WMI_PDEV_SET_HW_MODE_CMDID to put hardware
to dbs mode instead of wmi_init command. This fixes a few strange stability

There was no way to detect if the firmware crashed so add a warning. At the
moment the firmware is not restarted or anything like that, so when this
happens ath11k modules need to be reloaded.

Use MHI provided APIs to allocate and free MHI controller to
improve MHI host driver handling. This also fixes a memory leak
as the MHI controller was allocated but never freed.

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 some devices difference in chip-id should be enough to pick
the right BDF. Add another support for chip-id based BDF selection.
With this new option, ath10k supports 2 fallback options.
