Eliad Peller 6f157edb4d wl18xx: fallback to default conf in case of invalid conf file
If the wl18xx-conf.bin file is missing or invalid (e.g. due
to recent driver change), fallback to default configuration
instead of failing driver load.

Eyal Reizer bd763482c8 wl18xx: wlan_irq: support platform dependent interrupt types
* Interrupt request need to happen when the wilink chip is powered on and
  driving the wlan_irq line. This avoids spurious interrupt issues that
  are a result of different external pulls configuration on different
  platforms
* Allow working with wl18xx level-low and falling edge irqs by configuring
  wl18xx to invert the device interrupt

Nicolas Iooss a3fa71c40f wl18xx: show rx_frames_per_rates as an array as it really is
In struct wl18xx_acx_rx_rate_stat, rx_frames_per_rates field is an
array, not a number.  This means WL18XX_DEBUGFS_FWSTATS_FILE can't be
used to display this field in debugfs (it would display a pointer, not
the actual data).  Use WL18XX_DEBUGFS_FWSTATS_FILE_ARRAY instead.

This bug has been found by adding a __printf attribute to
wl1271_format_buffer.  gcc complained about "format '%u' expects
argument of type 'unsigned int', but argument 5 has type 'u32 *'".

Ido Reis e3b8bbb9e8 wl18xx: FDSP Code RAM Corruption fix
In PG2.0 there is an issue where PHY's FDSP Code RAM sometimes gets
corrupted when exiting from ELP mode. This issue is related to FDSP
Code RAM clock implementation.

PG2.1 introduces a HW fix for this issue that requires the driver to
change the FDSP Code Ram clock settings (mux it to ATGP clock instead
of its own clock).

This workaround uses PHY_FPGA_SPARE_1 register and is relevant to WL8
PG2.1 devices.

The fix is also backward compatible with older PG2.0 devices where the
register PHY_FPGA_SPARE_1 is not used and not connected.

The fix is done in the wl18xx_pre_upload function (must be performed
before uploading the FW code) and includes the following steps:

1. Disable FDSP clock
2. Set ATPG clock toward FDSP Code RAM rather than its own clock.
3. Re-enable FDSP clock

For this to work it is also necessary to convert everything

the TI wl18xx driver update can't possibly be right since
it just ignores the new channel width for lack of firmware

Johannes Berg e1a0c6b3a4 mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40
For VHT, many more bandwidth changes are possible. As a first
step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag
in the HT capabilities and instead introduce a bandwidth field
indicating the currently usable bandwidth to transmit to the
station. Of course, make all drivers use it.

To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get
the station as an argument, rather than the new capabilities,
so it can set up the new bandwidth field.

If the station is a VHT station and VHT bandwidth is in use,
also set the bandwidth accordingly.

Doing this allows us to get rid of the supports_40mhz flag as
the HT capabilities now reflect the true capability instead of
the current setting.

While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not
ignore HT cap overrides when MCS TX isn't supported (not that it
really happens...)

Victor Goldenshtein 1d6146659e wl18xx: add new phy configuration parameters for telec support
Add back-off settings to the wl18xx_mac_and_phy_params.  We had an
empty space where the new parameters are added, so this change doesn't
affect backwards-compatibility with older firmwares.

Update WL18XX_CONF_VERSION accordingly.

Arik Nemtsov 2fd8a3bb49 wl18xx: count HW block spare based correctly on keys
We have no idea how many VIFs there are requiring a special spare, we
know just about the number of keys set. Rename the counter appropriately
and toggle it whenever a special key is added/removed.
Previously this was only changed once, since it was toggled whenever
the actual spare was changed.

Eyal Shapira 0b70078c38 wlcore: support scan reports during periodic scan
FW API changed and now PERIODIC_SCAN_REPORT_EVENT is sent
in case results were found at the end of each sched scan
cycle. Previous FW was missing that and broke sched scan.

This API change is available from 18xx FW 8.5.0.0.27

[Arik - move changes to 18xx specific files, align FW structures to
latest for scan command]

Arik Nemtsov 98323895c0 wl18xx: limit Tx for the AP single-STA-in-PSM case
Treat a single connected STA in PSM as a slow link and regulate Tx speed
according to slow link priority/stop thresholds.
This allows us to avoid flooding the FW, while delivering decent
throughput to a peer in forced-PSM.

[Small simplification of the if statements -- Luca]

Arik Nemtsov f1626fd898 wlcore/wl18xx: change priority calculations for links
Update the 18xx FW status private part to include Tx related link
priorities. Introduce new HW ops to determine link priority per chip
family.

For 18xx the changes are:
- Suspended links are at most low priority and Tx for them is stopped
  beyond the suspend threshold.
- Active links now get their thresholds directly from FW
- There's a new "stop" threshold for active links, at which point a link
  stops receiving new packets.

Update the min 18xx FW version required to make sure suspended links
bitmap is advertised by the FW.

Yair Shapira c91ec5f3ad wl18xx: fix a bug in wl->num_rx_desc initialization
wl->num_rx_desc was mistakenly initialized with WL18XX_NUM_TX_DESCRIPTORS
but it should use WL18XX_NUM_RX_DESCRIPTORS instead.

This bug was passed unnoticed because currently both RX and TX descriptors
are initialized to the same value (32).
