Enable the feature flag to indicate the driver support for
preamble puncturing. Firmware will support this feature
by default from IEEE 802.11be onwards.
Configure the bitmap as part of VDEV start/restart and
peer association commands.

Add WMI support to process the EHT capabilities passed by
the firmware. Add required EHT specific definitions in
structures ath12k_band_cap and ath12k_wmi_svc_rdy_ext_parse.
For single_pdev chip such as WCN7850, only one pdev is created
and only one hardware is registered to mac80211. This one pdev
manages both 2.4 GHz radio and 5 GHz/6 GHz radio.

Currently there are about 60 channels for 6 GHz, then the size of
chan_list in struct scan_req_params which is 40 is not enough to
fill all the channel list of 6 GHz.
Use dynamic memory to save the channel list of scan.

In order to support different power levels of 6 GHz AP and client, new WMI
event for regulatory (WMI_REG_CHAN_LIST_CC_EXT_EVENTID) has been added in
firmware to provide new parameters required for 6 GHz regulatory rules.
Firmware advertises its capability of handling new event in WMI service ready
event. Based on that, host needs to set host_service_flags in WMI init command
to indicate that host supports processing of this WMI event. Based on
advertised host capability, firmware sends event WMI_REG_CHAN_LIST_CC_EXT_EVENTID.
This new event contains 2G/5G/6G reg rules with additional power value fields
for 6GHz and regd is built accordingly.

When vdev start/stop happens, response from firmware is received with delay
and hence there is a timeout before VDEV can be up/down.
Also, with maximum peers connected and when vdev stop occurs, firmware
will take time to clean up all the peers and vap queues.
In such cases as well, vdev start/stop response is sent by firmware with delay.
Increase the vdev setup timeout as recommended by firmware team.

Both PSOC_HOST_MAX_NUM_SS and WMI_MAX_NUM_SS are set to 8. The host assumes
that the values are the same but there's no check for that, so things will
break if either of the values change. It's simpler and safer to have just one
define so delete PSOC_HOST_MAX_NUM_SS and use WMI_MAX_NUM_SS everywhere.
No functional changes.

ath12k is a new mac80211 driver for Qualcomm Wi-Fi 7 devices, first
supporting QCN9274 and WCN7850 PCI devices. QCN9274 supports both AP
and station; WCN7850 supports only station mode. Monitor mode is not
(yet) supported. Only PCI bus devices are supported.
ath12k is forked from an earlier version of ath11k. It was simpler to
have a "clean start" for the new generation and not try to share the
code with ath11k. This makes maintenance easier and avoids major
changes in ath11k, which would have significantly increased the risk
of regressions in existing setups.
ath12k uses le32 and cpu_to_le32() macros to handle endian
conversions, instead of using the firmware byte swap feature utilized
by ath11k. There is only one kernel module, named ath12k.ko.
Currently ath12k only supports HE mode (IEEE 802.11ax) or older, but
work is ongoing to add EHT mode (IEEE 802.11be) support.
The size of the driver is ~41 kLOC and 45 files. To make the review
easier, this initial version of ath12k does not support Device Tree,
debugfs or any other extra features. Those will be added later, after
ath12k is accepted to upstream.
The driver is build tested by Intel's kernel test robot with both GCC
and Clang. Sparse reports no warnings. The driver is mostly free of
checkpatch warnings, albeit few of the warnings are omitted on
purpose, list of them here:
https://github.com/qca/qca-swiss-army-knife/blob/master/tools/scripts/ath12k/ath12k-check#L52
The driver has had multiple authors who are listed in alphabetical
order below.
