      wl12xx: Do end-of-transactions transfers only if needed · 606ea9fa
      由 Ido Yariv 提交于 
      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.

      wl12xx: Reorder data handling in irq_work · 8aad2464
      由 Ido Yariv 提交于 
      The FW has a limited amount of memory for holding frames. In case it
runs out of memory reserved for RX frames, it'll have no other choice
but to drop packets received from the AP. Thus, it is important to
handle RX data interrupts as soon as possible, before handling anything
else.

In addition, since there are enough TX descriptors to go around, it is
better to first send TX frames, and only then handle TX completions.

Fix this by changing the order of function calls in wl1271_irq_work.

      wl12xx: Remove private headers in wl1271_tx_reset · 50e9f746
      由 Ido Yariv 提交于 
      Frames in the tx_frames array include extra private headers, which must
be removed before passing the skbs to ieee80211_tx_status.

Fix this by removing any private headers in wl1271_tx_reset, similar to
how this is done in wl1271_tx_complete_packet.

      wl12xx: Don't rely on runtime PM for toggling power · 11251e7e
      由 Ido Yariv 提交于 
      Runtime PM might not always be enabled. Even if it is enabled in the
running kernel, it can still be temporarily disabled, for instance
during suspend. Runtime PM is opportunistic in nature, and should not be
relied on for toggling power.

In case the interface is removed and re-added while runtime PM is
disabled, the FW will fail to boot, as it is mandatory to toggle power
between boots. For instance, this can happen during suspend in case one
of the devices fails to suspend before the MMC host suspends, but after
mac80211 was suspended. The interface will be removed and reactivated
without toggling the power.

Fix this by calling mmc_power_save_host/mmc_power_restore_host in
wl1271_sdio_power_on/off functions. It will toggle the power to the chip
even if runtime PM is disabled. The runtime PM functions should still be
called to make sure runtime PM does not opportunistically power the chip
off (e.g. after resuming from system suspend).

      wl12xx: fix the path to the wl12xx firmwares · f62c317c

      In the linux-firmware git tree, the firmwares and the NVS are inside
the ti-connectivity directory.  Fix the filenames that the driver
looks for accordingly.
