Make it possible to name the producer side of a GPIO line using
a "gpio-line-names" property array, modeled on the
"clock-output-names" property from the clock bindings.
This naming is especially useful for:
- Debugging: lines are named after function, not just opaque
offset numbers.
- Exploration: systems where some or all GPIO lines are available
to end users, such as prototyping, one-off's "makerspace usecases"
users are helped by the names of the GPIO lines when tinkering.
This usecase has been surfacing recently.
The gpio-line-names attribute is completely optional.

If an existing 3270 terminal disconnects and reconnects with a
different size, the 3270 driver still works with the old size.
If the new dimensions are larger the output merely looks funny,
if the new dimensions are smaller the terminal is unusable.

The receive function may start processing an incoming packet while the
hard_iface is shut down in a different context. All called functions called
with the batadv_hard_iface object belonging to the incoming interface would
have to check whether the reference counter is still > 0.
This is rather error-prone because this check can be forgotten easily.
Instead check the reference counter when receiving the object to make sure
that all called functions have a valid reference.

The batadv_hardif_list list is checked in many situations and the items
in this list are given to specialized functions to modify the routing
behavior. At the moment each of these called functions has to check
itself whether the received batadv_hard_iface has a refcount > 0 before
it can increase the reference counter and use it in other objects.
This can easily lead to problems because it is not easily visible where
all callers of a function got the batadv_hard_iface object from and
whether they already hold a valid reference.
Checking the reference counter directly before calling a subfunction
with a pointer from the batadv_hardif_list avoids this problem.

There are network setups where the current bridge loop avoidance can't
detect bridge loops. The minimal setup affected would consist of two
LANs and two separate meshes, connected in a ring like that:
A...(mesh1)...B
| |
(LAN1) (LAN2)
| |
C...(mesh2)...D
Since both the meshes and backbones are separate, the bridge loop
avoidance has not enough information to detect and avoid the loop
in this case. Even if these scenarios can't be fixed easily,
these kind of loops can be detected.
This patch implements a periodic check (running every 60 seconds for
now) which sends a broadcast frame with a random MAC address on
each backbone VLAN. If a broadcast frame with the same MAC address
is received shortly after on the mesh, we know that there must be a
loop and report that incident as well as throw an uevent to let others
handle that problem.

caam_jr_alloc() used to return NULL if a JR device could not be
allocated for a session. In turn, every user of this function used
IS_ERR() function to verify if anything went wrong, which does NOT look
for NULL values. This made the kernel crash if the sanity check failed,
because the driver continued to think it had allocated a valid JR dev
instance to the session and at some point it tries to do a caam_jr_free()
on a NULL JR dev pointer.
This patch is a fix for this issue.

git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91 into fixes
Merge "at91: fixes for 4.6 #1" from Nicolas Ferre:
Here is a late fix for AT91. Sorry to have figure it out so late in the
development cycle but we had to confirm it was an error with the documentation
of two products.
So, as the compatibility string is in since 4.6-rc1 and that the previous one
works okay, it's a good opportunity to switch back to the one that works without
introducing a intermediary bug.
The revert on driver code and the removal of the useless additional
compatibility string will be queued for 4.7 through NAND/MTD.

mmc_select_hs200() and mmc_select_hs() will keep the timing
as before if switch fails. So it's meaningless to print the
failed switched mode outside based on the current host timing.
Furthermore, the original print is wrong, it should be:
pr_warn("%s: switch to %s failed\n",
mmc_hostname(card->host),
mmc_card_hs(card) ? "high-speed" :
(mmc_card_hs200(card) ? "hs200" : ""));
Since we already have error message in mmc_select_hs200(),
simply remove it outside.

Currently MMC core will keep going if HS200/HS timing switch failed
with -EBADMSG error by the assumption that the old timing is still valid.
However, for mmc_select_hs200 case, the signal voltage may have already
been switched. If the timing switch failed, we should fall back to
the old voltage in case the card is continue run with legacy timing.
If fall back signal voltage failed, we explicitly report an EIO error
to force retry during the next power cycle.

The HD-audio reconfig function got broken in the recent kernels,
typically resulting in a failure like:
snd_hda_intel 0000:00:1b.0: control 3:0:0:Playback Channel Map:0 is already present
This is because of the code restructuring to move the PCM and control
instantiation into the codec drive probe, by the commit [bcd96557bd0a:
ALSA: hda - Build PCMs and controls at codec driver probe]. Although
the commit above removed the calls of snd_hda_codec_build_pcms() and
*_build_controls() at the controller driver probe, the similar calls
in the reconfig were still left forgotten. This caused the
conflicting and duplicated PCMs and controls.
The fix is trivial: just remove these superfluous calls from
reconfig_codec().
