721ad3ca79 ath10k: add 10.4 fw specific htt msg definitions
New htt event table is added for 10.4 firmware. Following new htt
events are available only 10.4. adding this to generic htt event
table,
	HTT_T2H_MSG_TYPE_EN_STATS,
	HTT_T2H_MSG_TYPE_TX_FETCH_IND,
	HTT_T2H_MSG_TYPE_TX_FETCH_CONF,
	HTT_T2H_MSG_TYPE_TX_LOW_LATENCY_IND

b2297baa27 ath10k: add scan support for 10.4 fw
Existing non 10.4 firmware scan related events and commands are
matching with 10.4 firmware (except chan info event). Link general
start scan,stop scan, scan channel list configuration functions
to 10.4 wmi function table and add a new handler to parse 10.4
specific chan info event.

10.4 firmware has extra scan completion reason
WMI_SCAN_REASON_INTERNAL_FAILURE and new scan event
WMI_SCAN_EVENT_FOREIGN_CHANNEL_EXIT compared to previous firmware
versions. These things are added in respective enum.

373b48cfe7 ath10k: enable vdev and peer related operations for 10.4 fw
Most of existing vdev and peer related functions (vdev create,
vdev delete, vdev start, peer create, peer delete, peer flush, etc)
are reusable for 10.4 firmware. Link those general vdev and peer
functions to 10.4 wmi function table.

Existing general pktlog enable/disable, dbglog configuration functions
are reusable for 10.4 and add them also in wmi function table.

Also handle few wmi events (sevice rdy, echo, dbg msg, tbtt offset
update, dbg print) in ath10k_wmi_10_4_op_rx(). wow event is not
applicable in 10.4 firmware, have it under not implemented print.

3cec3be3d1 ath10k: handle 10.4 firmware wmi swba event
10.4 firmware swba event payload has space to accommodate upto
512 client traffic indication info & one p2p noa descriptor.
It's is not matching with exiting swba event format defined for
non 10.4 firmware. Non 10.4 firmware swba event format is designed
to support only upto only 128 client and four p2p notice of absence
descriptor.

following changes are done in this patch to enable ath10k to handle
10.4 firmware swba event,

 - link generic ath10k_wmi_event_host_swba() to handle 10.4 swba
   event in 10.4 wmi rx handler.

 - add 10.4 specific swba event structure wmi_10_4_host_swba_event.

 - new function ath10k_wmi_10_4_op_pull_swba_ev() to parse
   10.4 swba event.

 - increase tim_bitmap[] size in ath10k_vif to 64 to hold 512 station
   power save state.

a03fee347c ath10k: enhance swba event handler to adapt different size tim bitmap
Due to 512 client support in 10.4 firmware, size of tim ie is going
to be slightly higher than non 10.4 firmware. So, size of tim_bitmap
what is carried in swba event from 10.4 firmware is bit higher.

The only bottle neck to reuse existing swba handler
ath10k_wmi_event_host_swba() for 10.4 is that code designed to deal
with fixed size tim bitmap(ie, tim_info[].tim_bitmap in wmi_swba_ev_arg).
This patch removes such size limitation and makes it more suitable
to handle swba event which has different size tim bitmap.

All existing swba event parsing functions are changed to adapt this
change. Actual support to handle 10.4 swba event is added in next patch.
Only preparation is made in this patch.

089ab7a5af ath10k: remove ath10k_chanctx struct
In practice there's no point in having a copy of
chanctx_conf.

Most of the time the channel pointer (and band
along with it) is accessed and this can't change
after a chanctx is created because switching is
done using explicit chanctx swapping via
switch_vif_chanctx().

The only thing that can change within a
chanctx_conf and is used by the driver is
radar_enabled and channel width. These are however
always accessed in adequate mac80211 callback
context which guarantees safe access to the
chanctx data.

163f52647a ath10k: bypass PLL setting on target init for QCA9888
Some of of qca988x solutions are having global reset issue
during target initialization. Bypassing PLL setting before
downloading firmware and letting the SoC run on REF_CLK is fixing
the problem. Corresponding firmware change is also needed to set
the clock source once the target is initialized. Since 10.2.4
firmware is having this ROM patch, applying skip_clock_init only
for 10.2.4 firmware versions.

44b7d483b7 ath10k: fix inconsistent survey reports
In some cases some channel survey data was
reported incorrect.

Channel info events were expected to come in pairs
without and with COMPLETE flag set respectively
for each channel visit during scan.

The known deviation from this is rule for last
scan chan info and first (next) scan chan info
both have COMPLETE flag set. This was either
programmed with the intent of providing BSS cycle
count info or this is an artefact of firmware scan
state machine. Either way this is useless due to
short wraparound time, wraparound quirks and no
overflow notification.

Survey dumps now include only data gathered during
scan channel visits that can be computed
correctly.

This should improve hostapd ACS a little bit.

587f7031f3 ath10k: handle cycle counter wraparound
When QCA988X cycle counter HW register wraps
around it resets to 0x7fffffff instead of 0. All
other cycle counter related registers are divided
by 2 so they never wraparound themselves. QCA61X4
has a uniform CC and it wraparounds in a regular
fashion though.

Worst case wraparound time is approx 24 seconds
(2**31 / 88MHz). Since scan channel visit times
are max 5 seconds (offchannel case) it is
guaranteed there's been at most 1 wraparound and
it is possible to compute survey active time
value. It is, however, impossible to determine the
point at which Rx Clear Count has been divided by
two so it is not reported upon wraparound.

This fixes some occasional incorrect survey data
on QCA988X as some channels (depending on how/when
scan/offchannel requests were requested) would
have approx 24 sec active time which wasn't
actually the case.

This should improve hostapd ACS a little bit.

48f4ca34f3 ath10k: add new 4addr related fw_feature
Some firmware revisions pad 4th hw address in
Native Wifi Rx decap. This is the case with 10.x
and it was assumed that this is true for all
firmware images.

However QCA988X with 999.999.0.636 and QCA61X4
with WLAN.RM.2.0-00088 don't have the padding.
Hence add a feature flag indicating that the
padding isn't present so firmware images can
advertise it appropriately. This way driver will
behave as it was before with old firmware blobs
and doesn't cause any regressions from user
perspective.

Effectively this patch enables QCA988X with
999.999.0.636 and QCA61X4 with WLAN.RM.2.0-00088
to set up client bridging provided user has an
updated firmware blob.

77258d409c ath10k: enable pci soc powersaving
By using SOC_WAKE register it is possible to bring
down power consumption of QCA61X4 from 36mA to
16mA when associated and idle.

Currently the sleep threshold/grace period is at a
very conservative value of 60ms.

Contrary to QCA61X4 the QCA988X firmware doesn't
have Rx/beacon filtering available for client mode
and SWBA events are used for beaconing in AP/IBSS
so the SoC needs to be woken up at least every
~100ms in most cases. This means that QCA988X
is at a disadvantage and the power consumption
won't drop as much as for QCA61X4.

Due to putting irq-safe spinlocks on every MMIO
read/write it is expected this can cause a little
performance regression on some systems. I haven't
done any thorough measurements but some of my
tests don't show any extreme degradation.

The patch removes some explicit pci_wake calls
that were added in 320e14b8db51aa ("ath10k: fix
some pci wake/sleep issues"). This is safe because
all MMIO accesses are now wrapped and the device
is woken up automatically if necessary.

917826be9f ath10k: fix idle power consumption
mac80211 can update vif powersave state while
disconnected. Firmware doesn't behave nicely and
consumes more power than necessary if PS is
disabled on a non-started vdev. Hence
force-enable PS for non-running vdevs.

This reduces power drain on QCA61X4 from 88mA to
36mA when interface is up and not associated.
QCA988X wasn't measured.

76d870ed09 ath10k: enable ASPM
It is actually safe to enable ASPM after the
device is booted up.

This reduces power drain of QCA61X4 when driver is
simply loaded (no interface is up) from 31mA to
14mA. QCA988X wasn't measured but doesn't seem to
regress in any other way.
