Adjust driver behavior during FW boot. Proper sequence of

- FW prepares mailbox structure and reports IRQ "FW_READY"
- driver caches mailbox registers, marks mailbox readiness
- FW sends WMI_FW_READY event, ignore it
- FW sends WMI_READY event with some data

Add the hardware name, revision and update the pci_id table.

Currently there're two HW ref. designs available I'm aware of,
with 1.0.2 and 1.1 chip revisions. I've access and been using
the first one so far and this patch cover only it.

QCA9377 inherits most of the stuff (e.g. fw interfaces)
from QCA61x4 design, so the integration was pretty straightforward.

For the messages from host to target, shadow copy of CE descriptors
are maintained in source ring. Before writing actual CE descriptor,
first shadow copy is filled and then it is copied to CE address space.
To optimize in download path and to reduce d-cache pressure, removing
shadow copy of CE descriptors. This will also reduce driver memory
consumption by 33KB during on device probing.

Rajkumar Manoharan 765952e40d ath10k: cleanup copy engine send completion
The physical address necessary to unmap DMA ('bufferp') is stored
in ath10k_skb_cb as 'paddr'. ath10k doesn't rely on the meta/transfer_id
when handling send completion (htc ep id is stored in sk_buff control
buffer). So the unused output arguments {bufferp, nbytesp and transfer_idp}
are removed from CE send completion. This change is needed before removing
the shadow copy of copy engine (CE) descriptors in follow up patch.

Currently to avoid uncached memory access while filling up copy engine
descriptors, shadow descriptors are used. This can be optimized further
by removing shadow descriptors. To achieve that first shadow ring
dependency in ce_send is removed by creating local copy of the
descriptor on stack and make a one-shot copy into the "uncached"
descriptor.

Maharaja 62f77f095c ath10k: enable adaptive CCA
European Union has made it mandatory that all devices working in 2.4 GHz
has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1)
beginnig this year. The standard basically speaks about interferences
in 2.4Ghz band.
For example, when 802.11 device detects interference, TX must be stopped
as long as interference is present.

Adaptive CCA is a feature, when enabled the device learns from the
environment and configures CCA levels adaptively. This will improve
detecting interferences and the device can stop trasmissions till the
interference is present eventually leading to good performances in
varying interference conditions.

The patch includes code for enabling adaptive CCA for 10.2.4 firmware on
QCA988X.

Bob Copeland 8e8e54c490 wcn36xx: introduce per-channel ring buffer locks
wcn36xx implements a ring buffer for transmitted frames for each
(high and low priority) DMA channel.  The ring buffers are lockless:
new frames are inserted at the head of the queue, while finished
packets are reaped from the tail.

Unfortunately, the list manipulations are missing any kind of barriers
so are susceptible to various races: for example, a TX completion
handler might read an updated desc->ctrl before the head has actually
advanced, and then null out the ctl->skb pointer while it is still
being used in the TX path.

Simplify things here by adding a spin lock when traversing the ring.
This change increased stability for me without adding any noticeable
overhead on my platform (xperia z).

Zefir Kurtisi 56bae46427 ath9k: fix phyerror codes
Some of the ath9k_phyerr enums were wrong from the
beginning (and even before). Most of the time the
codes were used for counters to be displayed over
debugfs, which made this a non-functional issue.

Some (e.g. ATH9K_PHYERR_FALSE_RADAR_EXT) are used
for radar detection and require the correct code
to work as intended.

This patch includes:
a) fixes
  ATH9K_PHYERR_FALSE_RADAR_EXT:    24 => 36
  ATH9K_PHYERR_CCK_LENGTH_ILLEGAL: 32 => 28
  ATH9K_PHYERR_CCK_POWER_DROP:     33 => 29
  ATH9K_PHYERR_HT_CRC_ERROR:       34 => 32
  ATH9K_PHYERR_HT_LENGTH_ILLEGAL:  35 => 33
  ATH9K_PHYERR_HT_RATE_ILLEGAL:    36 => 34

b) extensions
  ATH9K_PHYERR_CCK_BLOCKER = 24
  ATH9K_PHYERR_HT_ZLF      = 35
  ATH9K_PHYERR_GREEN_FIELD = 37

Aside from the correction and completion made in
the enum, the patch also extends the display of
the related counters in the debugfs.

Anilkumar Kolli 1aaf8efba0 ath10k: disable PCI PS for QCA988X and QCA99X0
This patch disables PCI PS for QCA988X and QCA99X0, Since PCI PS is
validated for QCA6174, let it be enabled only for QCA6174. It would be
better to execute PCI PS related functions only for the supported devices.

PCI time out issue is observed with QCA99X0 on x86 platform, We will
disable PCI PS for QCA988X and QCA99X0 until PCI PS is properly implemented.

Taking and releasing ps_lock is causing higher CPU consumption. Michal Kazior
suggested ps_lock overhead to be reworked so that ath10k_pci_wake/sleep
functions are called less often, i.e. move the powersave logic up (only during
irq handling, tx path, submitting fw commands) but that's a bigger change and
can be implemented later.

Rajkumar Manoharan a70587b338 ath10k: configure copy engine 5 for HTT messages
Currently target to host (T2H) HTT messages are received at copy engine 1.
These messages are processed by HTC layer in both host and target.
To avoid HTC level processing overhead in both host and target,
the unused copy engine 5 is being used for receiving HTT T2H messages.
This will speedup the receive data processing as well as htt tx completion.
Hence host and target copy engine configuration tables are updated
to enable CE5 pipe. The in-direction HTT mapping is now pointing to CE5
for all HTT T2H.

Moreover HTT send completion messages are polled from HTC handler
as CE 4 is not interrupt-driven. For faster tx completion, CE4 polling
needs to be done whenever CE pipe which transports HTT Rx (target->host)
is processed. This avoids overhead of polling HTT messages from HTC
layer. Servicing CE 4 faster is helping to solve "failed to transmit
packet, dropping: -105".

Martin Blumenstingl 406df18f1f ath9k: Fix NF CCA limits for AR9287 and AR9227
The FreeBSD driver [0] uses the same 2G values as for the AR9280 chips.
Using the same values in ath9k results in much better throughput for me.

Before this patch I had a huge amount of packet loss (sometimes up to
40%) and the max transfer speed was somewhere around 5Mbit/s. With this
patch applied I have zero packet loss and ten times the throughput.
My device uses a AR9227 which is the PCI variant of the AR9287.

so that we have OTP binary before requesting for boardid-chipid. We get this
OTP data after parsing firmware-N.bin.

Manikanta Pubbisetty 0a51b343ab ath10k: add board 2 API support
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.

Avraham Stern 3b06d27795 cfg80211: Add multiple scan plans for scheduled scan
Add the option to configure multiple 'scan plans' for scheduled scan.
Each 'scan plan' defines the number of scan cycles and the interval
between scans. The scan plans are executed in the order they were
configured. The last scan plan will always run infinitely and thus
defines only the interval between scans.
The maximum number of scan plans supported by the device and the
maximum number of iterations in a single scan plan are advertised
to userspace so it can configure the scan plans appropriately.

When scheduled scan results are received there is no way to know which
scan plan is being currently executed, so there is no way to know when
the next scan iteration will start. This is not a problem, however.
The scan start timestamp is only used for flushing old scan results,
and there is no difference between flushing all results received until
the end of the previous iteration or the start of the current one,
since no results will be received in between.
