This reverts commit 13aa2fb692.
This commit broke QCN9074 initialisation:
[ 358.960477] ath11k_pci 0000:04:00.0: ce desc not available for wmi command 36866
[ 358.960481] ath11k_pci 0000:04:00.0: failed to send WMI_STA_POWERSAVE_PARAM_CMDID
[ 358.960484] ath11k_pci 0000:04:00.0: could not set uapsd params -105
As there's no fix available let's just revert it to get QCN9074 working again.

Now that the previous patch changed ath11k_dbg() to print the debug level
there's no need to have the level in the actual message anymore. So remove those.

Add support to process factory test mode commands (FTM) for calibration.
By default firmware start with NORMAL mode and to process the FTM commands
firmware needs to be restarted in FTM mode using module parameter ftm_mode.
The pre-request is all the radios should be down before starting the test.
When start command ATH11K_TM_CMD_TESTMODE_START is received, ar->state
is set to Test Mode. If the FTM command or event length is greater
than 256 bytes, it will be broken down into multiple segments and
encoded with TLV header if it is segmented commands, else it is sent
to firmware as it is.
On receiving UTF event from firmware, if it is segmented event, the driver
will wait until it receives all the segments and notify the complete
data to user application. In case the segmented sequence are missed or
lost from the firmware, driver will skip the already received partial data.
In case of unsegmented UTF event from firmware, driver notifies the
data to the user application as it comes. Applications handles
the data further.
Command to boot in ftm mode:
insmod ath11k ftm_mode=1

Currently, in ath11k_ahb_fw_resources_init(), iommu domain
mapping is done only for the chipsets having fixed firmware
memory. Also, for such chipsets, mapping is done only if it
does not have TrustZone support.
During deinitialization, only if TrustZone support is not there,
iommu is unmapped back. However, for non fixed firmware memory
chipsets, TrustZone support is not there and this makes the
condition check to true and it tries to unmap the memory which
was not mapped during initialization.
This leads to the following trace -

ath.git patches for v6.4. Major changes:
ath10k
* enable threaded napi on WCN3990
ath11k
* push MU-MIMO params from hostapd to hardware
* tx ack signal support for management packets
Including:
- Consolidate iommu_map/unmap functions. There have been
blocking and atomic variants so far, but that was problematic
as this approach does not scale with required new variants
which just differ in the GFP flags used.
So Jason consolidated this back into single functions that
take a GFP parameter. This has the potential to cause
conflicts with other trees, as they introduce new call-sites
for the changed functions. I offered them to pull in the
branch containing these changes and resolve it, but I am not
sure everyone did that. The conflicts this caused with
upstream up to v6.2-rc8 are resolved in the final merge
commit.
- Retire the detach_dev() call-back in iommu_ops
- Arm SMMU updates from Will:
- Device-tree binding updates:
* Cater for three power domains on SM6375
* Document existing compatible strings for Qualcomm SoCs
* Tighten up clocks description for platform-specific compatible strings
- Enable Qualcomm workarounds for some additional platforms that need them
- Intel VT-d updates from Lu Baolu:
- Add Intel IOMMU performance monitoring support
- Set No Execute Enable bit in PASID table entry
- Two performance optimizations
- Fix PASID directory pointer coherency
- Fix missed rollbacks in error path
- Cleanups
- Apple t8110 DART support
- Exynos IOMMU:
- Implement better fault handling
- Error handling fixes
- Renesas IPMMU:
- Add device tree bindings for r8a779g0
- AMD IOMMU:
- Various fixes for handling on SNP-enabled systems and
handling of faults with unknown request-ids
- Cleanups and other small fixes
- Various other smaller fixes and cleanups

As of commit a1a2b7125e ("of/platform: Drop static setup of IRQ
resource from DT core"), we need to use platform_get_irq() instead of
platform_get_resource() to get our IRQs because
platform_get_resource() simply won't get them anymore.
This was already fixed in several other Atheros WiFi drivers,
apparently in response to Zeal Robot reports. An example of another
fix is commit 9503a1fc12 ("ath9k: Use platform_get_irq() to get the
interrupt"). ath11k seems to have been missed in this effort, though.
Without this change, WiFi wasn't coming up on my Qualcomm sc7280-based
hardware. Specifically, "platform_get_resource(pdev, IORESOURCE_IRQ,
i)" was failing even for i=0.

Enable threaded NAPI on all ath11k targets. Unlike traditional
NAPI poll which runs in softirq context and on the core which
scheduled the NAPI, threaded NAPI makes use of kernel threads
which are under direct control of the scheduler and helps in
balancing the NAPI processing load across multiple CPUs thereby
improving throughput.
In the case of WCN6750, enabling threaded NAPI has improved
160 MHz RX throughput by nearly 400 Mbps. Similar gains can
be expected on other ath11k devices as well.

Add cold boot calibration support on WCN6750. Unlike other
chipsets where firmware(FW) is restarted after cold boot
calibration is completed, it is recommended not to restart
the firmware for WCN6750.
For WCN6750, FW sends both CAL_DONE & FW_READY QMI indication
to the driver after cold boot calibration is completed.
QMI message flow for WCN6750 with cold boot support:
FW_INIT_DONE to HOST -> CALIBRATION Mode to FW -> CAL_DONE to Host ->
FW_READY to Host -> MODE_ON to FW
QMI message flow for other chipsets with cold boot support:
FW_INIT_DONE to Host -> CALIBRATION Mode to FW -> FW_READY to Host ->
Trigger FW restart -> FW_INIT_DONE to HOST -> MODE_ON to FW
QMI message flow for chipsets without cold boot support:
FW_INIT_DONE to Host -> MODE_ON to FW

When the system shuts down, SMMU driver will be stopped and
will not assist in IOVA translations. SMMU driver expects all
of its consumers to shutdown before shutting down itself.
WCN6750 being one of the consumer device should not perform any
DMA operations after the SMMU has shutdown which will otherwise
result in SMMU faults.
SMMU driver will call the shutdown() callback of all its
consumer devices and the consumers shall stop further DMA
activity after the invocation of their respective shutdown()
callbacks.
Register the shutdown() callback to the platform core for WCN6750.
Change will not impact other AHB ath11k devices.

Commit 56c8ccf331 ("ath11k: Add register access logic for WCN6750")
regressed QCN9074. With the above mentioned commit, writes are failing
for some registers on QCN9074 although the device seems to work
normally.
ath11k_pci 0000:03:00.0: failed to set pcie link register0x01e0e0a8: 0xffffffff != 0x00000010
ath11k_pci 0000:03:00.0: failed to set sysclk: -110
PCIe devices in ath11k (QCA6390, WCN6855, QCN9074, WCN6750) use window
concept for register accesses. There are two schemes, dynamic & static
window.
In dynamic window scheme, a single window(region in the BAR) is mapped
either to CE or DP register windows at any give time. QCA6390 & WCN6855
follow this scheme for register accesses.
In static window scheme, CE & DP register windows are statically mapped
to separate regions with in the BAR so that there is no switching of
register windows between CE & DP register accesses. QCN9074 & WCN6750
follow this scheme although the window start offsets are different for
QCN9074 & WCN6750.
QCN9074 uses 3rd & 2nd window for DP & CE register accesses respectively
whereas WCN6750 uses 1st & 2nd window for DP & CE. In QCN9074, along with
2nd & 3rd windows, 1st window is also used for certain configurations
which commit 56c8ccf331 ("ath11k: Add register access logic for WCN6750")
did not account for and hence the regression.
Fix this by going back to the original way of accessing the registers on
QCN9074. Since this diverges from WCN6750 way of accessing registers, it
is required to register window_read32/window_write32() pci_ops for WCN6750.
We can also get rid of dp_window_idx & ce_window_idx members in hw_params,
so remove them.
Also add a new API ath11k_pcic_register_pci_ops() for registering pci_ops
to the ath11k core. This API checks for mandatory pci_ops() and reports
error if those are missing. Also initialize unused pci_ops to NULL.

As part of adding the support of WCN6750 to ath11k, bus_params
were moved to hw_params and this regressed the initialization
of WCN6750. By the time AHB resources are setup for WCN6750,
hw_params will not be initialized and therefore initialization
for WCN6750 will fail. This is applicable only for WCN6750,
no other device is impacted.
Fix this by moving the initialization of hw_params before
setting up AHB resources.

WCN6750 is non-DBS 2x2 11AX chipset. Unlike QCA6390 which is a
DBS (dual band simultaneous) solution (2 LMACs), WCN6750 has a
single LMAC supporting 2G, 5G and 6G bands but will operate only
on one band at any given point.
WCN6750 is a PCIe based solution, but it is attached to the WPSS
(Wireless Processor SubSystem) Q6 processor, hence it is enumerated
by the Q6 processor. It is registered to the APSS processor
(Application Processor SubSystem) as a platform device(AHB) and
remoteproc APIs are used to boot up or shutdown the device like
other AHB devices.
Also, Device information like BAR and it's size is not known to the
APSS processor as the chip is enumerated by WPSS Q6. These details
are fetched over QMI.
STA and AP modes are supported. Verified basic connectivity and ping
in both the modes.
An important point to note is that though WCN6750 is a PCIe device,
it cannot be attached to any other platform except on Qualcomm
Snapdragon SoCs due to the aforementioned reasons.

In ath11k, bus_params were added with an intention to hold
parameters related to bus (AHB/PCI), but this is not true
as some bus parameters being different between chipsets of
the same bus.
With the addition of WCN6750 to ath11k, bus parameters are
going to be entirely different among AHB devices. Therefore,
it is wise to move bus_params to hw_params and get rid of
bus_params entirely.
Also, mhi_support parameter is not used anywhere in the driver,
remove it from bus_params.

cold boot calibration is the process to calibrate all the channels
during the boot-up to avoid the calibration delay during the
channel change.
During the boot-up, firmware started in cold boot calibration mode
Firmware calibrate all channels and generate CalDb(DDR).
Subsequent wifi bringup will reuse the same CalDb.
Firmware is restarted in normal mode to continue the normal operation.
caldb memory address send to firmware through the QMI message.Firmware
use this address to store the caldb data and use it until next reboot.
This will give the improvement during the channel change. But it is
increasing the boot-up time(up to 15sec depend on number of radios).
So if the user want to reduce the boot-up time and accepting for channel
change delay, user can disable this feature using the module param
cold_boot_cal=0.

PCI devices like QCA6390 load the board file differently, add support for that
and the method is chosen using bus_params variables.
Add support to create board name for different targets. This board name is
used to parse the board data from board-2.bin for ahb/pci based targets.
As struct target_mem_chunk::vaddr was changed from 'u32' to 'u32 *' in
ath11k_qmi_assign_target_mem_chunk() vaddr assignments were changed to NULL to
avoid a compilation warning. IPQ8074 does not use the vaddr field for anything
so that change does not affect functionality.
At the moment this only supports board files with BIN type. Support for ELF
type, which seems to be more popular on QCA6390 devices, needs to be added later.
