It is expected that all pktlog events for 10.4 firmware based solutions
should come through CE8 where as in case of 10.2 firmware based solutions,
it should come through one of the HTT events (HTT_T2H_MSG_TYPE_PKTLOG).
But from experiments with 10.4 based solutions, it is observed that pktlog
event for ATH_PKTLOG_TYPE_TX_MSDU_ID is coming through HTT pktlog event.
Currently, we always parse with 10.2 pktlog header which will lead to
pktlog decoding issues (payload length mismatch exceptions)
For trace points, it is required to provide only the payload size. So
fixing this by simplifying the payload size calculation without the use of
ath10k pktlog headers.
While there, remove the unused ath10k pktlog headers.

In QCA4019, cycle counter wraparound is not tied to rx
clear counter. Each counter would wraparound individually
and after wraparound the respective counter will be reset
to 0x7fffffff while other counter still running unaffected.
Define a new wraparound type for this behaviour and handle
it separately so that rx clear counter wraparound is also
handled just like cycle counter. With this type of
wraparound we can accurately compute and report channel
active/busy time when any of the counter overflows.

QCA988X hw implements a different cycle counter wraparound

wraparound logic for these chipsets replace already available
bool hw_params member, has_shifted_cc_wraparound, with an
enum which could be extended to handle different wraparound
behaviour. This patch keeps the existing logic functionally

CCK hardware table mapping from QCA99X0 onwards got revised.
The CCK hardware rate values are in a proper order wrt. to
rate and preamble as below
ATH10K_HW_RATE_REV2_CCK_LP_1M = 1,
ATH10K_HW_RATE_REV2_CCK_LP_2M = 2,
ATH10K_HW_RATE_REV2_CCK_LP_5_5M = 3,

ATH10K_HW_RATE_REV2_CCK_SP_5_5M = 6,
ATH10K_HW_RATE_REV2_CCK_SP_11M = 7,
This results in reporting of rx frames (with CCK rates)
totally wrong for QCA99X0, QCA4019. Fix this by having
separate CCK rate table for these chipsets with rev2 suffix

To enable per peer stats feature we are reducing the number of peers.
Firmware has introduced tx stats feature. We have memory limitation in
firmware to add these additional bytes.
These are the new variables introduced in the firmware.
======== =======================
Variable Bytes required/per rate
======== =======================
TX success packets 1
TX failed packets 1
Retry packets 1
Success bytes 2
TX failed bytes 2
Retry bytes 2
Tx duration 4
Rate 1
Bw and AMPDU flags 1
Total 16 (because of allocation in word pattern)
Firmware sends these tx_stats in pktlog.
If we consider 4 feedbacks at a time, Frimware need about ~1K memory for coding
and 8192 bytes required / per rate [ 4*16*128(peers)].
To accommodate this firmware needs to reduce 10 peers.

qca4019 uses ahb instead of pci where it slightly differs in device
enumeration, clock control, reset control, etc. Good thing is that
ahb also uses copy engine for the data transaction. So, the most of
the stuff implemented in pci.c/ce.c are reusable in ahb case too.
Device enumeration in ahb case comes through platform driver/device
model. All resource details like irq, memory map, clocks, etc for
qca4019 can be fetched from of_node of platform device.
Simply flow would look like,
device tree => platform device (kernel) => platform driver (ath10k)
Device tree entry will have all qca4019 resource details and the same
info will be passed to kernel. Kernel will prepare new platform device
for that entry and expose DT info to of_node in platform device.
Later, ath10k would register platform driver with unique compatible name
and then kernels binds to corresponding compatible entry & calls ath10k
ahb probe functions. From there onwards, ath10k will take control of it
and move forward.
New bool flag CONFIG_ATH10K_AHB is added in Kconfig to conditionally
enable ahb support in ath10k. On enabling this flag, ath10k_pci.ko
will have ahb support. This patch adds only basic skeleton and few
macros to support ahb in the context of qca4019.

QCA6174 needs different board files based on board type. To make it easier to
distribute multiple board files and automatically choose correct board file
create a simple TLV file format following the same principles as with FW IEs.
The file is named board-2.bin and contain multiple board files. Each board file
then can have multiple names.
ath10k searches for file board-N.bin (where N is the interface version number
for the board file, just like we for firmware files) in /lib/firmware/*, for
example for qca99x0 it will try to find it here:
/lib/firmware/ath10k/QCA99X0/hw2.0/board-2.bin
If ath10k doesn't find board-2.bin then it will fallback to the old board.bin file.
This patch adds a simple name scheme using pci device id which for now will be
used by qca6174:
bus=%s,vendor=%04x,device=%04x,subsystem-vendor=%04x,subsystem-device=%04x
This removes the old method of having subsystem ids in ar->spec_board_id and
using that in the board file name.

encapsulation to the firmware. This is the default mode.
1: Use sofware crypto engine globally with raw mode TX/RX
encapsulation to the firmware.

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.

wpa_supplicant may need up to 4 vifs to have 2

Firmware 10.2.4.48-3 now supports management frames over HTT feature and has
ATH10K_FW_FEATURE_HAS_WMI_MGMT_TX. But as 10.2.4 branch has conflicting HTT ids
patch "ath10k: add ATH10K_FW_IE_HTT_OP_VERSION" is needed to fix the issue.

Target to host HTT messages are conflicting between 10.x and other
firmware revisions. By maintaining separate HTT T2H tables for each
firmware revisions (main, 10x and tlv) similar to WMI abstraction,
solves the conflicts. Add ATH10K_FW_IE_HTT_OP_VERSION so that the firmware can
advertise the HTT interface to ath10k.
This fix is needed to get management frames over HTT (ie.
ATH10K_FW_FEATURE_HAS_WMI_MGMT_TX disabled) working with 10.2.4.48-2 firmware.
Otherwise there will be unknown htt events and nothing works:
[30087.438343] ath10k_pci 0000:02:00.0: htt event (19) not handled
[30087.448691] ath10k_pci 0000:02:00.0: htt event (19) not handled
[30149.032974] ath10k_pci 0000:02:00.0: htt event (19) not handled
If the firmware does not have ATH10K_FW_IE_HTT_OP_VERSION use the main HTT
interface. That way old firmware images will still work.

A frequent request have been to be able to provide calibration data from a
file as some of the AP devices store the calibration data on an MTD partition.
This patchset adds support for that and also makes it easier to add Device Tree
support later on.
The calibration data is found by using the id string provided by dev_name()
using this format:
cal-<bus>-<id>.bin
With PCI the id string contains bus, slot and func values. For example for a
PCI device in bus 2 slot 0, ath10k will try to retrieve a calibration data from
a file:
/lib/firmware/ath10k/cal-pci-0000:02:00.0.bin
The calibration data sequence is:
1. Check with request_firmware() if there's a calibration file
("cal-<bus>-<id>.bin") on the filesystem for this device. If yes, use that. If
not, goto 2
2. Check if otp.bin is able to successfully load the calibration data
from OTP. If yes, use that. If not, goto 3.
4. Print an error message that no calibration data found and stop driver
initialization for this device.
