694440d93b wl12xx: disable AP-mode-specific quirks
The current wl12xx fw (7.3.0.0.77) supports both STA and AP mode, and
we no longer use AP-mode-specific quirks.

WL12XX_QUIRK_END_OF_TRANSACTION is still used for certain HWs, while
WL12XX_QUIRK_LPD_MODE is not used anymore.

6d158ff38d wl12xx: Add support for HW channel switch
The wl12xx FW supports HW channel switch.  If we don't use it,
sometimes the firmware gets confused when recalibrating to the new
channel, causing RX problems.  This commit adds HW channel switch
support by implementing the channell_switch op.

cabb81c9a8 wl12xx: allow 11a AP-mode for wl127x devices
There was a check preventing 127x devices from using the 11a band when
operating as AP. Since we now support this functionality, remove the
check.

With this patch, a 11a AP starts ok on 127x cards.

c690ec816f wl12xx: update commands & events
Change the commands and events according to the new fw api
(fw >= 6/7.3.0.0.75).

The main change is the replacement of JOIN/DISCONNECT commands,
with ROLE_START/ROLE_STOP commands.

The use of these commands should be preceded by the ROLE_ENABLE
command (allocating role resources), and followed by the
ROLE_DISABLE command (freeing role resources).

95dac04f88 wl12xx: Support routing FW logs to the host
A recently added feature to the firmware enables the driver to retrieve
firmware logs via the host bus (SDIO or SPI).

There are two modes of operation:
1. On-demand: The FW collects its log in an internal ring buffer. This
   buffer can later be read, for example, upon recovery.
2. Continuous: The FW pushes the FW logs as special packets in the RX
   path.

Reading the internal ring buffer does not involve the FW. Thus, as long
as the HW is not in ELP, it should be possible to read the logs, even if
the FW crashes.

A sysfs binary file named "fwlog" was added to support this feature,
letting a monitor process read the FW messages. The log is transferred
from the FW only when available, so the reading process might block.

47684808fd wl12xx: support FW TX inactivity triggers
In AP mode we register for the MAX_TX_RETRY and INACTIVE_STA events.
Both are reported to the upper layers as a TX failure in the offending
stations.

In STA mode we register only for the MAX_TX_RETRY event. A TX failure is
interpreted as a loss of connection.

Support for IEEE80211_HW_REPORTS_TX_ACK_STATUS has been removed to avoid
the inherent race condition of a mac80211 TX failure counter in addition
to the FW counter.

This patch depends on "mac80211: allow low level driver to report packet
loss"

Only send dummy packet when not in AP mode.

[Even though the DUMMY_PACKET_EVENT_ID and the
STA_REMOVE_COMPLETE_EVENT_ID events are defined to the same value, we
need to treat them separately in the code.  Keep the check and enable
STA_REMOVE_COMPLETE_EVENT_ID for AP mode and DUMMY_PACKET_EVENT_ID for
STA.  Moved one warning to a cleaner place.  Use WL1271_TID_MGMT for
dummy packets -- Luca]

Boot sequence support FREF clock and TCXO clock.
WL128x has two clocks input - TCXO and FREF.
TCXO is the main clock of the device, while FREF is used to sync

case the FREF will be used as the WLAN/BT main clock.

change in main.c; remove some unnecessary debug prints and comments;

606ea9fa0b wl12xx: Do end-of-transactions transfers only if needed
On newer hardware revisions, there is no need to write the host's
counter at the end of a RX transaction. The same applies to writing the
number of packets at the end of a TX transaction.

It is generally a good idea to avoid unnecessary SDIO/SPI transfers.
Throughput and CPU usage are improved when avoiding these.

Send the host's RX counter and the TX packet count only if needed, based
on the hardware revision.
