Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:
====================
Please pull this batch of updates intended for 3.16...
For the mac80211 bits, Johannes says:
"Here I just have Heikki's rfkill GPIO cleanups.
The ARM/tegra patch is OK with the maintainer (Stephen). Let me know of
any problems."
and;
"We have a whole bunch of work on CSA by Andrei, Luca and Michal, but
unfortunately it doesn't seem quite complete yet so it's still disabled.
There's some TDLS work from Arik, and the rest is mostly minor fixes and
cleanups."
For the NFC bits, Samuel says:
"This is the NFC pull request for 3.16. We have:
- STMicroeectronics st21nfca support. The st21nfca is an HCI chipset and
thus relies on the HCI stack. This submission provides support for tag
redaer/writer mode (including Type 5) and device tree bindings.
- PM runtime support and a bunch of bug fixes for TI's trf7970a.
- Device tree support for NXP's pn544. Legacy platform data support is
obviously kept intact.
- NFC Tag type 4B support to the NFC Digital stack.
- SOCK_RAW type support to the raw NFC socket, and allow NCI
sniffing from that. This can be extended to report HCI frames and also
proprietarry ones like e.g. the pn533 ones."
For the iwlwifi bits, Emmanuel says:
"Eran continues to work on new devices, Eyal is still digging in
the rate control stuff, and Johannes added new functionality to the
debug system we have in place now along with a few cleanups he made
on the way. That's pretty much it."
and;
"Avri continues to work on the power code and Eran is improving the
NVM handling as a preparations for new devices on which he works
with Liad. Luca cleans up a bit the code while working on CSA. I have
the regular BT Coex stuff and a small lockdep fix. Johannes has his
regular amount of clean ups and improvements, the main one is the
ability to leave 2 chains open to improve diversity and hence the
throughput in high attenuation scenarios."
and;
"The regular amount of housekeeping here. I merged iwlwifi-fixes.git to
be able to add the patch you didn't want in wireless.git at that stage
of the -rc cycle. Luca has a few preparations for CSA implementation
and also what seems to be a bugfix for P2P but hasn't caused issues
we could notice."
For the Atheros bits, Kalle says:
"For ath10k Michal did various small fixes on how we handle
hardware/firmware problems and he also fixed two memory leaks."
Also included are a couple of pulls from the wireless tree to
avoid/resolve merge issues...
