6af1de2e4e ath10k: mark PM functions as __maybe_unused
When CONFIG_PM_SLEEP is disabled, we get a compile-time
warning:

drivers/net/wireless/ath/ath10k/pci.c:3417:12: error: 'ath10k_pci_pm_resume' defined but not used [-Werror=unused-function]

 static int ath10k_pci_pm_suspend(struct device *dev)

Rather than fixing the #ifdef, this just marks both functions
as __maybe_unused, which is a more robust way to do this.

393b706cf2 ath10k: configure and enable the wakeup capability
ACPI will rely on device driver to tell it if the device could support
wakeup function when system in D3 state.

This has caused some platform can't support remote wakeup correctly,
because the ACPI wakeup GPE is not enabled, hence registers the .set_wakeup
callback to handle it if device supports wakeup.

Tested with QCA6174 hw3.0, firmware ('WLAN.RM.4.4.1-00008-QCARMSWP-1')

32faa3f0ee ath10k: add the PCI PM core suspend/resume ops
The actual PCI suspend/resume in ath10k has been handled in wow.c,
but in the case of the device doesn't support remote wakeup,
the .hif_suspend() and .hif_resume() will never be handled.

  ath10k_wow_op_suspend()
  {
	if (WARN_ON(!test_bit(ATH10K_FW_FEATURE_WOWLAN_SUPPORT,
		    ar->running_fw->fw_file.fw_features))) {
		ret = 1;
		goto exit;
	}

	....

	ret = ath10k_hif_suspend(ar);
  }

So register the PCI PM core to support the suspend/resume if the device
doesn't support remote wakeup.

c0cc00f250 ath10k: activate user space firmware loading again
In commit 9f5bcfe933 ("ath10k: silence firmware file probing
warnings") the firmware loading was changed from request_firmware() to
request_firmware_direct() to silence some warnings in case it fails.
request_firmware_direct() directly searches in the file system only and
does not send a hotplug event to user space in case it could not find
the firmware directly.
In LEDE we use a user space script to extract the calibration data from
the flash memory which gets triggered by the hotplug event. This way the
firmware gets extracted from some vendor specific partition when the
driver requests this firmware. This mechanism does not work any more
after this change.

irq_wq in struct ath10k_sdio is a remnant from an earlier

the struct member survived.

c9353bf483 ath10k: fix napi_poll budget overflow
In napi_poll, the budget number is used to control the amount of packets
we should handle per poll to balance the resource in the system.

In the list of the amsdu packets reception, we check if there is budget
count left and handle the complete list of the packets, that it will have
chances the very last list will over the budget leftover.

So adding one more parameter - budget_left, this would help while
traversing the list to avoid handling more than the budget given.

f35a7f91f6 ath10k: fix memory leak in rx ring buffer allocation
The rx ring buffers are added to a hash table if
firmware support full rx reorder. If the full rx
reorder support flag is not set before allocating
the rx ring buffers, none of the buffers are added
to the hash table.

There is a race condition between rx ring refill and
rx buffer replenish from napi poll. The interrupts are
enabled in hif start, before the rx ring is refilled during init.
We replenish buffers from napi poll due to the interrupts which
get enabled after hif start. Hence before the entire rx ring is
refilled during the init, the napi poll replenishes a few buffers
in steps of 100 buffers per attempt. During this rx ring replenish
from napi poll, the rx reorder flag has not been set due to which
the replenished buffers are not added to the hash table

Set the rx full reorder support flag before we allocate
the rx ring buffer to avoid the memory leak.

Commit a53e35db70 ("reset: Ensure drivers are explicit when requesting

to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

be5b4f4002 ath10k: push peer type to target for TDLS peers
WMI interface for all the firmwares(except QCA6174) does not include the
type of peer(default/bss/tdls) requested during peer creation, therefore
target creates a default peer.

TDLS implementation on 10.4 firmware requires host to configure the
peer type(tdls) for TDLS peers. This patch adds peer type parameter to the
existing WMI interface for peer creation to accommodate this requirement.

Tested this change on QCA9888(10.4-3.5.1-00018) and QCA988x(10.2.4.70.9-2)
with ping tests for AP/STA modes.

810fe818d6 ath10k: extend wmi service map to accommodate new services
Though there is room to accommodate 512 services in wmi service
ready event, target uses only first 4-bits of each 32-bit word for
advertising wmi services thereby limiting max wmi services to 64.

TDLS implementation for 10.4 firmwares introduces new wmi services by
making use of remaining unused bits of each 32-bit word, therefore the
wmi service mapping in host needs to be extended.

This patch adds the logic to extend the wmi SVCMAP to accommodate new
wmi services.

cc914a5500 ath10k: configure rxnss_override for QCA9984
QCA9984 hardware can do 4x4 at 80Mhz, but only 2x2 at 160Mhz.

First, report this to user-space by setting the max-tx-speed
and max-rx-speed vht capabilities.

Second, if the peer rx-speed is configured, and if we
are in 160 or 80+80 mode, and the peer rx-speed matches
the max speed for 2x2 or 1x1 at 160Mhz (long guard interval),
then use that info to set the peer_bw_rxnss_override appropriately.

Without this, a 9984 firmware will not use 2x2 ratesets when
transmitting to peer (it will be stuck at 1x1), because
the firmware would not have configured the rxnss_override.

e509e59477 ath10k: use complete VHT chan width for 160MHz workaround
The ath10k firmware doesn't announce its VHT channel width capabilities in
the vht_cap information from the "service ready event" arguments. The
driver must therefore check whether the 160MHz short GI bit is set and
whether the driver still doesn't set the bits for the 160/80+80 MHz
capabilities.

The two bits for the channel width are a two bit integer and not two
separate bits which cannot be parsed without the knowledge of the other
bit. Using IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160_80PLUS80MHZ (b10..) as a
mask for this task doesn't make any sense. The correct mask for the VHT
channel width should be used instead to make this check more readable.

03a016f894 ath10k: define structures for CE ctrl/misc register
Define structures for the copy engine ctrl/misc registers,
that includes CE CMD halt, watermark source, watermark destination,
host IE ring, source, destination and dmax ring.

This adds support to avoid the conditional compilation,
code optimization and dynamic configuration of the copy engine
register map for respective hardware bus interface.

9a993cc1ea ath10k: fix the logic of limiting tdls peer counts
The original idea is to limit the maximum TDLS peer link, but the logic
is always false, and never be able to restrict the number of TDLS peer
creation.

Fix the logic here and also move the checking earlier, so that it could
avoid to handle the failure case, e.g disable the tdls peer, delete the
peer and also vdev count cleanup.

a9f5f287fa ath10k: add BMI parameters to fix calibration from DT/pre-cal
QCA99X0, QCA9888, QCA9984 supports calibration data in
either OTP or DT/pre-cal file. Current ath10k supports
Calibration data from OTP only.

If caldata is loaded from DT/pre-cal file, fetching board id
and applying calibration parameters like tx power gets failed.

error log:
[   15.733663] ath10k_pci 0000:01:00.0: failed to fetch board file: -2
[   15.741474] ath10k_pci 0000:01:00.0: could not probe fw (-2)

This patch adds calibration data support from DT/pre-cal
file.  Below parameters are used to get board id and
applying calibration parameters from cal data.

		EEPROM[OTP]	FLASH[DT/pre-cal file]
Cal param	0x700		0x10000
Board id	0x10		0x8000

Tested on QCA9888 with pre-cal file.

13c3b26a71 ath10k: increase BMI timeout
When testing a 9888 chipset NIC, I notice it often takes
almost 2 seconds, and then many times OTP fails, probably due
to the two-second timeout.

[ 2269.841842] ath10k_pci 0000:05:00.0: bmi cmd took: 1984 jiffies (HZ: 1000), rv: 0
[ 2273.608185] ath10k_pci 0000:05:00.0: bmi cmd took: 1986 jiffies (HZ: 1000), rv: 0
[ 2277.294732] ath10k_pci 0000:05:00.0: bmi cmd took: 1989 jiffies (HZ: 1000), rv: 0

So, increase the BMI timeout to 3 seconds.

79e6882158 ath10k: go back to using dma_alloc_coherent() for firmware scratch memory
This reverts commit b057886524 ("ath10k: do not use coherent memory for
allocated device memory chunks") in 2015 which converted this allocation from
dma_map_coherent() to kzalloc() / dma_map_single().

The current problem manifests when using later model NICs with larger
(>700KiB) scratch spaces in memory.  Although the kzalloc call
succeeds, the software IOMMU TLB code (via dma_map_single()) panics
because it can't find 700KiB of linear physmem bounce buffers for DMA.
Now, this is a bit of a silly failure mode for the dma map API,
but it's what we currently have to play with.

In these cases, doing kzalloc() works fine, but the dma_map_single()
call fails.

After chatting with Linus briefly about this, it indeed should be
using dma_alloc_coherent() for doing larger device memory allocation
that requires some kind of physical address mapping.

You're not supposed to be using kzalloc and dma_map_* calls for
large memory regions, and I'm guessing not for long-held mappings
either.  Typically dma mappings should be temporary for DMA,
not long held like these.

Now, since hopefully the major annoying underlying problem has also been
addressed (ie, ath10k is no longer tears down all of these allocations
and reallocates them every time the vdevs are brought down) fragmentation
should stop being such a touchy issue.  If it is though, using
dma_alloc_coherent() use gets us access to the CMB APIs too relatively
easily and ideally we would be allocating memory early in boot for
exactly these reasons.

c1dd8016ae ath10k: fix reported HT MCS rates with NSS > 1
The QCA4019 firmware 10.4-3.2.1-00050 reports only HT MCS rates between
0-9. But 802.11n MCS rates can be larger than that. For example a 2x2
device can send with up to MCS 15.

The firmware encodes the higher MCS rates using the NSS field. The actual
calculation is not documented by QCA but it seems like the NSS field can be
mapped for HT rates to following MCS offsets:

 * NSS 1: 0
 * NSS 2: 8
 * NSS 3: 16
 * NSS 4: 24

This offset therefore has to be added for HT rates before they are stored
in the rate_info struct.

Chipsets like QCA6584 have support for SDIO so add initial SDIO bus support to
ath10k. With this patch we have the low level HTC protocol working and it's
possible to boot the firmware, but it's still not possible to connect or
anything like. More changes are needed for full functionality. For that reason
we print during initialisation:

fcd2113363 ath10k: htc: refactorization
Code refactorization:

Moved the code for ep 0 in ath10k_htc_rx_completion_handler
to ath10k_htc_control_rx_complete.

This eases the implementation of SDIO/mbox significantly since
the ep_rx_complete cb is invoked directly from the SDIO/mbox
hif layer.

Since the ath10k_htc_control_rx_complete already is present
(only containing a warning message) there is no reason for not
using it (instead of having a special case for ep 0 in
ath10k_htc_rx_completion_handler).

ea1a3ddf62 ath10k: htc: move htc ctrl ep connect to htc_init
This patch moves the HTC ctrl service connect from
htc_wait_target to htc_init.

This is done in order to make sure the htc ctrl service
is setup properly before hif_start is called.

The reason for this is that we want the HTC ctrl service
callback to be initialized before the target sends the
HTC ready message.

The ready message will always be transmitted on endpoint 0
(which is always assigned to the HTC control service) so it
makes more sense if HTC control has been connected before the
ready message is received.

Since the service to pipe mapping is done as a part of
the service connect, the get_default_pipe call is redundant
and was removed.
