xt_socket is useful for matching sockets with IP_TRANSPARENT and
taking some action on the matching packets. However, it lacks the
ability to match only a small subset of transparent sockets.
Suppose there are 2 applications, each with its own set of transparent
sockets. The first application wants all matching packets dropped,
while the second application wants them forwarded somewhere else.
Add the ability to retore the skb->mark from the sk_mark. The mark
is only restored if a matching socket is found and the transparent /
nowildcard conditions are satisfied.
Now the 2 hypothetical applications can differentiate their sockets
based on a mark value set with SO_MARK.
iptables -t mangle -I PREROUTING -m socket --transparent \
--restore-skmark -j action
iptables -t mangle -A action -m mark --mark 10 -j action2
iptables -t mangle -A action -m mark --mark 11 -j action3

commit 681f130f39e10 ("netfilter: xt_socket: add XT_SOCKET_NOWILDCARD
flag") added a potential NULL dereference if an old iptables package
uses v0 of the match.
Fix this by removing the test on @info in fast path.
IPv6 can remove the test as well, as it uses v1 or v2.

xt_socket module can be a nice replacement to conntrack module
in some cases (SYN filtering for example)
But it lacks the ability to match the 3rd packet of TCP
handshake (ACK coming from the client).
Add a XT_SOCKET_NOWILDCARD flag to disable the wildcard mechanism.
The wildcard is the legacy socket match behavior, that ignores
LISTEN sockets bound to INADDR_ANY (or ipv6 equivalent)
iptables -I INPUT -p tcp --syn -j SYN_CHAIN
iptables -I INPUT -m socket --nowildcard -j ACCEPT

With IP early demux added in linux-3.6, we perform TCP lookup in IP
layer before iptables hooks.
We can avoid doing a second lookup in xt_socket.

During device resume, the touch resume function is called after display's
resume. In this case, the ft5x06's resume function needs to wait for
200ms because of reset requirement. Defer the touch resume to a workqueue
to reduce the total device resume time. For this an optional DT property
is added to enable this on targets that need this feature.

In the current implementation AICL is not re-run if its already
in progress. However in case where ICL gets updated while AICL
is in progress, the updated ICL value is not considered unless
AICL re-runs again. Handle this by re-running AICL irrespective of
the AICL status.

Current the smbcharger is splitting the ICL and charge current fairly
naively. This can cause problems where one charger is FCC limited and
another charger is ICL limited, causing a lot of wasted charge current.
Do a better current distribution to maximize the amount of charge
current going into the battery. By default, raise the ICL ratio of the
primary charger up to 60% to avoid issues with system load prematurely
causing the charger to current limit. Lower the FCC ratio back to 50% to
accommodate this.
Also, make both of these properties configurable through module
parameters and device tree in order to accommodate differences in pcb
and battery limitation.

At 9V, the smbcharger is more efficient at a switching frequency of
1MHz. Switch to this when the driver detects that it is in HVDCP 2.0
mode. Also, switch the VFIX clamping voltage threshold so that the
frequency is maintained.
