effea9688d ath10k: cleanup debug messages in core.c
Fix them to follow the general logging style in ath10k.

While at it, add print id chip_id to the debug log.

b52b7688ac ath10k: rename ATH10K_DBG_CORE to BOOT
core.c mostly deals with driver and firmware starting related
actions. And we can use the boot level also in other components,
like PCI and HTT.

03fc137b50 ath10k: set the UART baud rate to 19200
When configuring the host_interests over BMI, set the UART
baud rate to 19200. This is valid for QCA988X_2.0 devices.

kvalo: found during code review, there should not be any functionality
changes

e01ae68c5d ath10k: check chip id from the soc register during probe
ath10k doesn't support qca988x hw1.0 boards anymore. Unfortunately
the PCI id is the same in hw1.0 and hw2.0 so ath10k tries to use
hw1.0 boards anyway. But without hw1.0 workarounds in place
ath10k just crashes horribly.

To avoid using hw1.0 boards at all add a chip id detection
and fail the probe if hw1.0 is detected:

[ 5265.786408] ath10k: ERROR: qca988x hw1.0 is not supported
[ 5265.786497] ath10k: Unsupported chip id 0x043200ff
[ 5265.786574] ath10k: could not register driver core (-95)
[ 5265.793191] ath10k_pci: probe of 0000:02:00.0 failed with error -95

Also add a warning if there's an unknown chip id but continue
the boot process normally anyway.

drop all code (especially workarounds) for those units.

affd321733 ath10k: implement device recovery
Restart the hardware if FW crashes.

If FW crashes during recovery we leave the
hardware in a "wedged" state to avoid recursive
recoveries.

When in "wedged" state userspace may bring
interfaces down (to issue stop()) and then bring
one interface (to issue start()) to reload
hardware manually.

293850575d ath10k: store firmware files in memory
Different FW versions may provide different
functions thus mean different hw capabilities
advertised to mac80211.

It is safe to swap firmware files on disk during
driver/device runtime without worries.

818bdd16b2 ath10k: defer hw setup to start/stop mac80211 hooks
This fixes suspend-to-disk. The hardware is now
re-initialized upon freeze/thaw properly.

This also makes suspend/resume re-initialize the
hardware as WoWLAN support is not done yet.

With some little work it should be possible to
support hw reconfiguration for hw/fw recovery.

HW must be initialized once before registering to
mac80211 because FW determinates what hw
capabilities can be advertised.

1a1b8a889d ath10k: move free_vdev_map initialization
This is necessary for hw reconfiguration to work.
Since mac80211 is not calling remove_interface()
is such case we must reset free_vdev_map.

Also use a define instead of a hardcoded value for
vdev map initialization.

8cd13cad1c ath10k: decouple suspend code
Split up fw-related and hw-related suspension code.

Although we don't advertise WoW support to
mac80211 yet it's useful to keep the code in
suspend/resume hooks.

At this point there's no need to keep pci pm ops.
In case of WoW mac80211 calls ath10k_suspend()
which should take care of entering low-power mode.
In case WoW is not available mac80211 will go
through regular interface teradown and use start/stop.

5e3dd157d7 ath10k: mac80211 driver for Qualcomm Atheros 802.11ac CQA98xx devices
Here's a new mac80211 driver for Qualcomm Atheros 802.11ac QCA98xx devices.
A major difference from ath9k is that there's now a firmware and
that's why we had to implement a new driver.

The wiki page for the driver is:

http://wireless.kernel.org/en/users/Drivers/ath10k

The driver has had many authors, they are listed here alphabetically:
