Kalle Valo da3a9d3c15 ath11k: refactor debugfs code into debugfs.c
If CONFIG_ATH11K_DEBUGFS is disabled there are warnings debug.c:

drivers/net/wireless/ath/ath11k/debug.c:36:20: warning: 'htt_bp_lmac_ring' defined but not used [-Wunused-variable]
   36 | static const char *htt_bp_lmac_ring[HTT_SW_LMAC_RING_IDX_MAX] = {
      |                    ^~~~~~~~~~~~~~~~
drivers/net/wireless/ath/ath11k/debug.c:15:20: warning: 'htt_bp_umac_ring' defined but not used [-Wunused-variable]
   15 | static const char *htt_bp_umac_ring[HTT_SW_UMAC_RING_IDX_MAX] = {
      |                    ^~~~~~~~~~~~~~~~

Fix this by refactoring debugfs code to debugfs.c. This also reduces the number
of ifdefs in debug.c and makes it easier to maintain the code.

Govind Singh 1399fb87ea ath11k: register MHI controller device for QCA6390
Modem Host Interface (MHI) is a communication protocol to communicate with
external Qualcomm modems and Wi-Fi chipsets over high speed peripheral buses.
Even though MHI doesn’t dictate underlying physical layer, protocol and MHI
stack is structured for PCI based devices.

Register directly with MHI subsystem as a MHI device driver for firmware
download to QCA6390.

Karthikeyan Periyasamy 9d11b7bff9 ath11k: add support for spectral scan
spectral scan control interface is exposed through debugfs eentry.
Relayfs is used to collect the spectral data. These interfaces are
similar to ath10k spectral.

spectral debugfs interfaces are below,

Karthikeyan Periyasamy bd6478559e ath11k: Add direct buffer ring support
Add direct buffer ring (dbring) with helper API, which is used by the
spectral scan. Initialise the direct buffer ring based on the dma ring
capability, which get announced in the wmi service ready extended event.
This ring is slightly changed from data path rings. Compare to data path
ring this ring shares the hp and tp address to firmware though WMI commands.
Also the replenish buffer size is derived from firmware announcement.
driver receive indication through WMI event

Pradeep Kumar Chitrapu 2a63bbca06 ath11k: add thermal cooling device support
Thermal cooling device support is added to control the temperature by
throttling the data transmission for the given duration. Throttling is
done by suspending all data tx queues by given percentage of time. The
thermal device allows user to configure duty cycle.

Throttling can be disabled by setting the duty cycle to 0. The cooling
device can be found under /sys/class/thermal/cooling_deviceX/.
Corresponding soft link to this device can be found under phy folder.

/sys/class/ieee80211/phy*/device/cooling_device.

To set duty cycle as 40%,

Arnd Bergmann a45ceea501 ath11k: fix debugfs build failure
When CONFIG_ATH11K_DEBUGFS is disabled, but CONFIG_MAC80211_DEBUGFS
is turned on, the driver fails to build:

drivers/net/wireless/ath/ath11k/debugfs_sta.c: In function 'ath11k_dbg_sta_open_htt_peer_stats':
drivers/net/wireless/ath/ath11k/debugfs_sta.c:416:4: error: 'struct ath11k' has no member named 'debug'
  ar->debug.htt_stats.stats_req = stats_req;
    ^~

It appears that just using the former symbol is sufficient here,
adding a Kconfig dependency takes care of the corner cases.

Kalle Valo d5c65159f2 ath11k: driver for Qualcomm IEEE 802.11ax devices
ath11k is a new driver for Qualcomm IEEE 802.11ax devices, first
supporting only IPQ8074 SoC using the shared memory AHB bus. ath11k
uses mac80211 and supports AP, Station and Mesh modes.

Even though ath11k has some similar code as with ath10k (especially
the WMI layer) it was concluded to be simpler to have a "clean start"
for ath11k code base and not try to share the code with ath10k. This
makes maintenance easier and avoids major changes in ath10k, which
would have significantly increased the risk of regressions in existing
setups.

Even though the driver is very similar with ath10k but there are major
differences as well. The datapath is completely different. ath11k
supports multiple MACs, called "soc" in the firmware interface. And
there's only one WMI interface to support.

Currently ath11k supports only IEEE 802.11ac mode, but patches for
802.11ax are available and they will be submitted after ath11k is
accepted to upstream.

The firmware images are available from ath11k-firmware repository but
they will be also submitted to linux-firmware:

https://github.com/kvalo/ath11k-firmware

This was tested with firmware version WLAN.HK.2.1.0.1-00629-QCAHKSWPL_SILICONZ-1.

The driver has had multiple authors who are listed in alphabetical
order below.
