wifi: ath12k: remove the unused scan_events from ath12k_wmi_scan_req_arg

As done for ath11k, lets keep on cleaning up struct ath12k_wmi_scan_req_arg by
removing the unused scan_events. Also remove the underlying union & struct
construct as it isn't needed anymore. No functionnal changes.

wifi: ath12k: Remove unused scan_flags from struct ath12k_wmi_scan_req_arg

As we did for ath11k lets remove the unused scan_flags from struct
ath12k_wmi_scan_req_arg. This will prevent us from using out of sync values
between WMI_SCAN_XXX & scan_f_xxx bitfield.
While at it remove the underlying wrapping struct/union construct as it serves
no purpose anymore.

wifi: ath12k: implement handling of P2P NoA event

The Notice of Absence (NoA) attribute is used by the P2P Group Owner to
signal its absence due to power save timing, concurrent operation, or
off-channel scanning. It is also used in the P2P Presence Request-Response
mechanism.

The NoA attribute shall be present in the P2P IE in the beacon frames
transmitted by a P2P Group Owner when a NoA schedule is being advertised,
or when the CTWindow is non-zero.

So add support to update P2P information after P2P GO is up through
event WMI_P2P_NOA_EVENTID, and always put it in probe resp.

Create p2p.c and p2p.h for P2P related functions and definitions.

wifi: ath12k: subscribe required word mask from rx tlv

Most of the RX descriptors fields are currently not used in the
ath12k driver. Hence add support to selectively subscribe to the
required quad words (64 bits) within msdu_end and mpdu_start of
rx_desc.

Add compact rx_desc structures and configure the bit mask for Rx TLVs
(msdu_end, mpdu_start, mpdu_end) via registers. With these registers
SW can configure to DMA the partial TLV struct to Rx buffer.

Each TLV type has its own register to configure the mask value.
The mask value configured in register will indicate if a particular
QWORD has to be written to rx buffer or not i.e., if Nth bit is enabled
in the mask Nth QWORD will be written and it will not be written if the
bit is disabled in mask. While 0th bit indicates whether TLV tag will be
written or not.

Advantages of Qword subscription of TLVs
- Avoid multiple cache-line misses as the all the required fields
of the TLV are within 128 bytes.
- Memory optimization as TLVs + DATA + SHINFO can fit in 2k buffer
even for 64 bit kernel.

Add support to process WMI_TLV_SERVICE_PEER_METADATA_V1A_V1B_SUPPORT
service bit. If this service bit is set by firmware, then it expects
host to set rx_peer_meta_data_ver in wmi_resource_config's flags2
with value 3 for QCN9274 to indicate as V1B meta version. If this is
not set firmware crash is seen during peer addition.

Hence, if WMI_TLV_SERVICE_PEER_METADATA_V1A_V1B_SUPPORT service bit
is set by firmware, set correct peer metadata version to avoid

wifi: ath12k: fetch correct pdev id from WMI_SERVICE_READY_EXT_EVENTID

Currently while fetching for pdev id from WMI_SERVICE_READY_EXT_EVENTID
we consider 32 bit pdev_id in ath12k_wmi_caps_ext_params structure. But
Firmware sends lower 16 bit for pdev id along with higher 16 bit for
hw_link_id. Due to this wrong pdev id is fetched. This wrong pdev id
when used for WMI commands leads to Firmware crash.

Hence fetch the correct pdev id considering only the lower 16 bits.

wifi: ath12k: Consolidate WMI peer flags

Currently wmi.h has two separate set of definitions for peer
flags. One set of flags is defined in enum wmi_tlv_peer_flags, and,
except for the last three, are named WMI_TLV_PEER_*. The other set of
flags are defined as macros, and are named WMI_PEER_*. The last three
macros have the same name as the last three wmi_tlv_peer_flags
enumerators.

The code only uses the WMI_PEER_* names; the WMI_TLV_PEER_* names are
unused. So as a first step in consolidation, remove all the
WMI_TLV_PEER_* names.

But since having an enum to define all the flags is actually a good
thing since that provides a handle by which to refer to the entire set
of flags, recast the WMI_PEER_* macros into enumerators.

Compile tested only.

wifi: ath12k: add keep backward compatibility of PHY mode to avoid firmware crash

In a special WCN7855 firmware release the EHT (IEEE 802.11be) support has
been disabled for size reduction. Currently ath12k always enables EHT PHY
mode during vdev start but with the special firmware that will cause a
firmware crash during vdev start in firmware initialisation. This is
because the firmware will use the EHT mode to allocate resources but as
the EHT mode is not available in the firmware, there's an internal
conflict and the firmware will crash.

To fix the crash check the WMI_TLV_SERVICE_11BE flag to see if the firmware
supports EHT. If EHT is not supported downgrade the PHY mode to HE
(IEEE 802.11ax).

This does not impact QCN9274, because WMI_SERVICE_11BE is always enabled
for QCN9274, then eht_cap->has_eht will always set for it, and the logic
of this patch will not take effect and the PHY mode will not down grade
for it.

if so, send the GPIO information to firmware. When the firmware detects
hardware rfkill is enabled by the user, it will report it using
WMI_RFKILL_STATE_CHANGE_EVENTID. When ath12k receive the event, it will set
the value of rfkill_radio_on based on whether radio_state is equal to
WMI_RFKILL_RADIO_STATE_ON, then send WMI_PDEV_PARAM_RFKILL_ENABLE to

wifi: ath12k: WMI support to process EHT capabilities

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.

wifi: ath12k: change to use dynamic memory for channel list of scan

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.

wifi: ath12k: Add support to parse new WMI event for 6 GHz regulatory

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.

wifi: ath12k: increase vdev setup timeout

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.

wifi: ath12k: wmi: delete PSOC_HOST_MAX_NUM_SS

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.

wifi: ath12k: driver for Qualcomm Wi-Fi 7 devices

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.
