Instead of selecting MSI config based on magic numbers, make
the assignment based on HW revision. The logic is similar to
the selection of HW params. This improves readability of the
code and also simplifies new additions.

Unlike other ATH11K PCIe devices which are enumerated by APSS
processor (Application Processor SubSystem), WCN6750 gets
enumerated by the WPSS Q6 processor (Wireless Processor SubSystem);
In simple terms, though WCN6750 is PCIe device, it is not attached
to the APSS processor, APSS will not know of such a device being
present in the system and therefore WCN6750 will be registered as
a platform device to the kernel core like other supported AHB
devices.

WCN6750 needs both AHB and PCI APIs for it's operation, it uses
AHB APIs for device probe/boot and PCI APIs for device setup and
register accesses. Because of this nature, it is referred as a
hybrid bus device.

Refactor PCI code to support hybrid bus devices like WCN6750.

In order to add the support for WCN6750 in ATH11K , it is
required to move certain PCI definitions to the header file.
As a result, add ATH11K_PCI_* prefix to these definitions.

Also, change the scope of certain PCI APIs that are required
to enable WCN6750 from static to global.

commit cfee8793 ("ath10k: enable napi on RX path for
sdio") introduced napi for SDIO and updated the htt interface for high
latency devices.

These changes breaks USB, so USB code must be updated to use napi as
well in order to have a working RX path.

Currently ath11k will wait 11d scan complete while add interface in
ath11k_mac_op_add_interface(), when system resume without enable
wowlan, ath11k_mac_op_add_interface() is called for each resume, thus
it increase the resume time of system. And ath11k_mac_op_hw_scan()
after ath11k_mac_op_add_interface() also needs some time cost because
the previous 11d scan need more than 5 seconds when 6 GHz is enabled,
then the scan started event will indicated to ath11k after the 11d
scan completed.

While 11d scan/hw scan is running in firmware, if ath11k update channel
list to firmware by WMI_SCAN_CHAN_LIST_CMDID, then firmware will cancel
the current scan which is running, it lead the scan failed. The patch
commit 9dcf6808 ("ath11k: add 11d scan offload support") used
finish_11d_scan/finish_11d_ch_list/pending_11d to synchronize the 11d
scan/hw scan/channel list between ath11k/firmware/mac80211 and to avoid
the scan fail.

Add wait operation before ath11k update channel list, function
ath11k_reg_update_chan_list() will wait until the current 11d scan/hw
scan completed. And remove the wait operation of start 11d scan and
waiting channel list complete in hw scan. After these changes, resume
time cost reduce about 5 seconds and also hw scan time cost reduced
obviously, and scan failed not seen.

The 11d scan is sent to firmware only one time for each interface added
in mac.c, and it is moved after the 1st hw scan because 11d scan will
cost some time and thus leads the AP scan result update to UI delay.
Currently priority of ath11k's hw scan is WMI_SCAN_PRIORITY_LOW, and
priority of 11d scan in firmware is WMI_SCAN_PRIORITY_MEDIUM, then the
11d scan which sent after hw scan will cancel the hw scan in firmware,
so change the priority to WMI_SCAN_PRIORITY_MEDIUM for the hw scan which
is in front of the 11d scan, thus it will not happen scan cancel in
firmware.

Currently ath11k only download the same regdb.bin file for all WCN6855
chips, actually ath11k needs to distinguish all different WCN6855 chips.

This is to re-use the string type which include bus, chip id, board id,
vendor, device, subsystem-vendor, subsystem-device and variant for
WCN6855 to distinguish different regdb in board-2.bin.

ath11k will first load board-2.bin and search in it for the regdb data
with the above parameters, if matched one regdb data, then download it
to firmware, if not matched any one, then ath11k will download the file
regdb.bin to firmware.

Add enum value ATH11K_BD_IE_REGDB and enum type ath11k_bd_ie_regdb_type
to distinguish regdb data and board data since they are in the same file
board-2.bin.

This only take effect for WCN6855 which supports regdb in hardware parameters.

Currently ath11k does not send the country code to firmware after device
recovery, as a result the regdomain info is reported from firmware by
default. Regdomain info is important, so ath11k also need to restore

required for QCN550x support, to provide an abstraction over the
underlying EEPROM format.

ar9003_get_spur_chan_ptr. This may also be required for QCN550x support,

This makes the code clearer since set11nRateFlags currently sets
both the rate flags and chain sel. This may also be required for
QCN550x support, where the rate flags and chain sel are in separate

When more clients (128) are connected, the UL data traffic
KPI measurement is low compared to single client. This issue
is due to more CPU cycles spent on the peer lookup operation
with more clients. So reduce the peer lookup operation by
modifying the linear based lookup operation into the rhash
based lookup operation. This improve the peak throughput
measurement. Since this is a software algorithm change, it is
applicable for all the platforms.

TCP UL 128 Clients test case Observation (64bit system):
Previous: ~550 Mbps
Now	: ~860 Mbps

Sometimes it has a variant value which read from DT or SMBIOS by
ath11k, and meanwhile it does not have the matched board name in
board-2.bin, then it will failed at boot up phase.

Add fallback board name which removed variant value and search again
in board-2.bin when failed with variant and try to load the board
data again to increase boot up success rate.

In Qualcomm ARM platforms there is WL_EN pin and other power regulators
which can be controlled at platform side to completely reset the chip.
For most of x86 and other platforms, the chip is connected via PCIe M.2
interface, and there is no way to control WL_EN pin. Instead the host
driver needs to reset the chip via PCIE_SOC_GLOBAL_RESET hardware
register, just like ath11k does currently.

But when using PCIE_SOC_GLOBAL_RESET there are some hardware registers
which are not cleared/restored. To handle those cases we can enable
PLATFORM_CAP_PCIE_GLOBAL_RESET QMI host capability to tell the firmware
to do some platform specific operations after firmware download.

This does not fix any known issues, but is recommended by the firmware
team, so enable the capability on QCA6390 and WCN6855 PCI devices. It is
currently unclear if this should be enabled also on QCN9074, so leave it
disabled for now. On AHB devices this is not needed as they don't use
PCIE_SOC_GLOBAL_RESET.

Reason is mhi_deassert_dev_wake() from mhi_device_put() is called
but mhi_assert_dev_wake() from __mhi_device_get_sync() is not called
in progress of recovery. Commit 8e055992 ("bus: mhi: core:
Skip device wake in error or shutdown state") add check for the
pm_state of mhi in __mhi_device_get_sync(), and the pm_state is not
the normal state untill recovery is completed, so it leads the
dev_wake is not 0 and above warning print in mhi_pm_disable_transition()
while checking mhi_cntrl->dev_wake.

Add check in ath11k_pci_write32()/ath11k_pci_read32() to skip call
mhi_device_put() if mhi_device_get_sync() does not really do wake,
then the warning gone.

ieee80211_reconfig() of mac80211 is the main function for recovery of
each ieee80211_hw and ath11k, and ath11k_core_reconfigure_on_crash()
is the main function for recovery of ath11k_base, it has more than
one ieee80211_hw and ath11k for each ath11k_base, so it need to add
synchronization between them, otherwise it has many issue.

For example, when ath11k_core_reconfigure_on_crash() is not complete,
mac80211 send a hw scan request to ath11k, it leads firmware crash,
because firmware has not been initialized at that moment, firmware
is only finished downloaded and loaded, it can not receive scan
command.

Currently ath11k has device recovery logic, it is introduced by this
patch "ath11k: Add support for subsystem recovery" which is upstream
by https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=ath11k-bringup&id=3a7b4838b6f6f234239f263ef3dc02e612a083ad.

The patch is for AHB devices such as IPQ8074, it has remote proc module
which is used to download the firmware and boots the processor which
firmware is running on. If firmware crashed, remote proc module will
detect it and download and boot firmware again. Below command will
trigger a firmware crash, and then user can test feature of device
recovery.

Test command:
echo assert > /sys/kernel/debug/ath11k/qca6390\ hw2.0/simulate_fw_crash
echo assert > /sys/kernel/debug/ath11k/wcn6855\ hw2.0/simulate_fw_crash

Unfortunately, QCA6390 is PCIe bus, it does not have the remote proc
module, it use mhi module to communicate between firmware and ath11k.
So ath11k does not support device recovery for QCA6390 currently.

This patch is to add the extra logic which is different for QCA6390.
When firmware crashed, MHI_CB_EE_RDDM event will be indicate by
firmware and then ath11k_mhi_op_status_cb which is the callback of
mhi_controller will receive the MHI_CB_EE_RDDM event, then ath11k
will start to do recovery process, ath11k_core_reset() calls
ath11k_hif_power_down()/ath11k_hif_power_up(), then the mhi/ath11k
will start to download and boot firmware. There are some logic to
avoid deadloop recovery and two simultaneous recovery operations.
And because it has muti-radios for the soc, so it add some logic
in ath11k_mac_op_reconfig_complete() to make sure all radios has
reconfig complete and then complete the device recovery.

Also it add workqueue_aux, because ab->workqueue is used when receive
ATH11K_QMI_EVENT_FW_READY in recovery process(queue_work(ab->workqueue,
&ab->restart_work)), and ath11k_core_reset will wait for max
ATH11K_RESET_TIMEOUT_HZ for the previous restart_work finished, if
ath11k_core_reset also queued in ab->workqueue, then it will delay
restart_work of previous recovery and lead previous recovery fail.

ath11k recovery success for QCA6390/WCN6855 after apply this patch.

ath11k_peer_find_by_addr states via lockdep that ab->base_lock must be
held when calling that function in order to protect the list. All
callers except ath11k_mac_op_unassign_vif_chanctx have that lock
acquired when calling ath11k_peer_find_by_addr. That lock is also not
transitively held by a path towards ath11k_mac_op_unassign_vif_chanctx.
The solution is to acquire the lock when calling
ath11k_peer_find_by_addr inside ath11k_mac_op_unassign_vif_chanctx.

I am currently working on a static analyser to detect missing locks and
this was a reported case. I manually verified the report by looking at
the code, but I do not have real hardware so this is compile tested
only.

Currently after the hardware restart triggered from the driver,
the station interface connection remains intact, since a disconnect
trigger is not sent to userspace. This can lead to a problem in
targets where the wifi mac sequence is added by the firmware.

After the target restart, its wifi mac sequence number gets
reset to zero. Hence AP to which our device is connected will receive
frames with a  wifi mac sequence number jump to the past, thereby
resulting in the AP dropping all these frames, until the frame
arrives with a wifi mac sequence number which AP was expecting.

To avoid such frame drops, its better to trigger a station disconnect
upon target hardware restart which can be done with API
ieee80211_reconfig_disconnect exposed to mac80211.

The other targets are not affected by this change, since the hardware
params flag is not set.

It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ)
for requesting IRQ's resources any more, as they can be not ready yet in
case of DT-booting.

platform_get_irq() instead is a recommended way for getting IRQ even if
it was not retrieved earlier.

It also makes code simpler because we're getting "int" value right away
and no conversion from resource to int is required.
