Add dtsi for imx6q and imx6dl with non-common blocks moved into there.
Major differences between imx6dl and imx6q:
* Dual vs. Quad cores
* single vs. dual IPU
* 128 vs. 256 KB OCRAM
* imx6q: ECSPI5, OpenVG (GC355), SATA
* imx6dl: I2C4, PXP, EPDC, LCDIF
* iomuxc/pads definition

i.MX6 Quad and i.MX6 DualLite is similar enough to share one dtsi
file, so rename imx6q.dtsi to imx6qdl.dtsi preparing for the addition
of imx6dl support.
Another member of i.MX6 series i.MX6 SoloLite is different enough
from the other two, so it will stand as a separate dtsi. That's why
we rename to imx6qdl.dtsi not imx6.dtsi.

This mxs usbphy is only needs to be on after system boots
up, and software never needs to control it anymore.
Meanwhile, usbphy's parent needs to be notified if usb
is suspend or not. So we design below mxs usbphy usage:
- usbphy1_gate and usbphy2_gate:
Their parents are dummy clock, we only needs to enable
it after system boots up.
- usbphy1 and usbphy2
Usage reserved bit for this clock, in that case, the refcount
will be updated, but without hardware changing.

The tqma53 is an embedded module that has some features on board (e.g. emmc),
but mostly just provides access to them on its interface.
Going along with the imx53.dtsi, the tqma53.dtsi specifies the existing
devices and their pinctrl for this module. All devices that are not on the
module are disabled by default and need to be enabled in a baseboard DT.

Pull ARM fixes from Russell King:
"I was going to hold these off until v3.8 was out, and send them with a
stable tag, but as everyone else is pushing much bigger fixes which
Linus is accepting, let's save people from the hastle of having to
patch v3.8 back into working or use a stable kernel.
Looking at the diffstat, this really is high value for its size; this
is miniscule compared to how the -rc6 to tip diffstat currently looks.
So, four patches in this set:
- Punit Agrawal reports that the kernel no longer boots on MPCore due
to a new assumption made in the GIC code which isn't true of
earlier GIC designs. This is the biggest change in this set.
- Punit's boot log also revealed a bunch of WARN_ON() dumps caused by
the DT-ification of the GIC support without fixing up non-DT
Realview - which now sees a greater number of interrupts than it
did before.
- A fix for the DMA coherent code from Marek which uses the wrong
check for atomic allocations; this can result in spinlock lockups
or other nasty effects.
- A fix from Will, which will affect all Android based platforms if
not applied (which use the 2G:2G VM split) - this causes
particularly 'make' to misbehave unless this bug is fixed."
* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:
ARM: 7641/1: memory: fix broken mmap by ensuring TASK_UNMAPPED_BASE is aligned
ARM: DMA mapping: fix bad atomic test
ARM: realview: ensure that we have sufficient IRQs available

Pull networking fixes from David Miller:
1) Revert iwlwifi reclaimed packet tracking, it causes problems for a

2) Work limiting code in brcmsmac wifi driver can clear tx status

3) rtlwifi USB driver processes wrong SKB, fix from Larry Finger.
4) l2tp tunnel delete can race with close, fix from Tom Parkin.
5) pktgen_add_device() failures are not checked at all, fix from Cong
Wang.
6) Fix unintentional removal of carrier off from tun_detach(),

7) Don't leak socket reference counts and ubufs in vhost-net driver,

8) vmxnet3 driver gets it's initial carrier state wrong, fix from Neil
Horman.
9) Protect against USB networking devices which spam the host with 0
length frames, from Bjørn Mork.
10) Prevent neighbour overflows in ipv6 for locally destined routes,
from Marcelo Ricardo. This is the best short-term fix for this, a
longer term fix has been implemented in net-next.
11) L2TP uses ipv4 datagram routines in it's ipv6 code, whoops. This
mistake is largely because the ipv6 functions don't even have some
kind of prefix in their names to suggest they are ipv6 specific.
From Tom Parkin.
12) Check SYN packet drops properly in tcp_rcv_fastopen_synack(), from

16) Fix error handling in ipv6 GRE tunnel transmit, from Tommi Rantala.
17) Protect XEN netback driver against hostile frontend putting garbage

Ian Campbell.
18) SCTP authentication keys should be cleared out and released with
kzfree(), from Daniel Borkmann.
19) L2TP is a bit too clever trying to maintain skb->truesize, and ends
up corrupting socket memory accounting to the point where packet
sending is halted indefinitely. Just remove the adjustments
entirely, they aren't really needed. From Eric Dumazet.
20) ATM Iphase driver uses a data type with the same name as the S390
headers, rename to fix the build. From Heiko Carstens.
21) Fix a typo in copying the inner network header offset from one SKB

In sctp_setsockopt_auth_key, we create a temporary copy of the user
passed shared auth key for the endpoint or association and after
internal setup, we free it right away. Since it's sensitive data, we
should zero out the key before returning the memory back to the
allocator. Thus, use kzfree instead of kfree, just as we do in
sctp_auth_key_put().

We have conflicting type qualifiers for "freg_t" in s390's ptrace.h and the
iphase atm device driver, which causes the compile error below.
Unfortunately the s390 typedef can't be renamed, since it's a user visible api,
nor can I change the include order in s390 code to avoid the conflict.
So simply rename the iphase typedef to a new name. Fixes this compile error:

We have received multiple reports of mmap failures when running with a
2:2 vm split. These manifest as either -EINVAL with a non page-aligned
address (ending 0xaaa) or a SEGV, depending on the application. The
issue is commonly observed in children of make, which appears to use
bottom-up mmap (assumedly because it changes the stack rlimit).
Further investigation reveals that this regression was triggered by
394ef6403abc ("mm: use vm_unmapped_area() on arm architecture"), whereby
TASK_UNMAPPED_BASE is no longer page-aligned for bottom-up mmap, causing
get_unmapped_area to choke on misaligned addressed.
This patch fixes the problem by defining TASK_UNMAPPED_BASE in terms of
TASK_SIZE and explicitly aligns the result to 16M, matching the other
end of the heap.

This happens because the DMA allocation code is not respecting atomic
allocations correctly.
GFP flags should not be tested for GFP_ATOMIC to determine if an
atomic allocation is being requested. GFP_ATOMIC is not a flag but
a value. The GFP bitmask flags are all prefixed with __GFP_.
The rest of the kernel tests for __GFP_WAIT not being set to indicate
an atomic allocation. We need to do the same.

Some early GIC implementations return zero for the first distributor
CPU routing register. This means we can't rely on that telling us
which CPU interface we're connected to. We know that these platforms
implement PPIs for IRQs 29-31 - but we shouldn't assume that these
will always be populated.
So, instead, scan for a non-zero CPU routing register in the first
32 IRQs and use that as our CPU mask.

Playing with skb->truesize is tricky, especially when
skb is attached to a socket, as we can fool memory charging.
Just remove this code, its not worth trying to be ultra

For sensitive data like keying material, it is common practice to zero
out keys before returning the memory back to the allocator. Thus, use

Ian Campbell says:
====================
The Xen netback implementation contains a couple of flaws which can
allow a guest to cause a DoS in the backend domain, potentially
affecting other domains in the system.
CVE-2013-0216 is a failure to sanity check the ring producer/consumer
pointers which can allow a guest to cause netback to loop for an
extended period preventing other work from occurring.
CVE-2013-0217 is a memory leak on an error path which is guest
triggerable.
The following series contains the fixes for these issues, as previously
included in Xen Security Advisory 39:
http://lists.xen.org/archives/html/xen-announce/2013-02/msg00001.html
Changes in v2:
- Typo and block comment format fixes
- Added stable Cc

A buggy or malicious frontend should not be able to confuse netback.
If we spot anything which is not as it should be then shutdown the
device and don't try to continue with the ring in a potentially
hostile state. Well behaved and non-hostile frontends will not be
penalised.
As well as making the existing checks for such errors fatal also add a
new check that ensures that there isn't an insane number of requests
on the ring (i.e. more than would fit in the ring). If the ring
contains garbage then previously is was possible to loop over this
insane number, getting an error each time and therefore not generating
any more pending requests and therefore not exiting the loop in
xen_netbk_tx_build_gops for an externded period.
Also turn various netdev_dbg calls which no precipitate a fatal error
into netdev_err, they are rate limited because the device is shutdown
afterwards.
This fixes at least one known DoS/softlockup of the backend domain.
