Seems like we've had more fixes than usual this release cycle, but
there's nothing in particular that we're doing differently. Perhaps it's
just one of those cycles where more people are finding more regressions
(and/or that the latency of when people actually test what's been in
the tree for a while is catching up so that we get the bug reports now).
The bigger changes here are are for TI and Marvell platforms:
* Timing changes for GPMC (generic localbus) on OMAP causing some largeish
DTS deltas.
* Fixes to window allocation on PCI for mvebu touching drivers/ stuff. Patches
have acks from subsystem maintainers where needed.
* A fix from Thomas for a botched DT conversion in drivers/edma.
There's a handful of other fixes for the above platforms as well as sunxi,
at91, i.MX. I also included a MAINTAINER update for Broadcom, and a trivial
move of a binding doc.

The netlink conflict dealt with moving to netlink_capable() and
netlink_ns_capable() in the 'net' tree vs. supporting 'tc' operations
in non-init namespaces. These were simple transformations from
netlink_capable to netlink_ns_capable.
The Altera driver conflict was simply code removal overlapping some

Introduce gpiod_get_optional() and gpiod_get_index_optional() helpers
that make it easier for drivers to handle optional GPIOs.
Currently in order to handle optional GPIOs, a driver needs to special
case error handling for -ENOENT, such as this:
gpio = gpiod_get(dev, "foo");
if (IS_ERR(gpio)) {
if (PTR_ERR(gpio) != -ENOENT)
return PTR_ERR(gpio);
gpio = NULL;
}
if (gpio) {
/* set up GPIO */
}
With these new helpers the above is reduced to:
gpio = gpiod_get_optional(dev, "foo");
if (IS_ERR(gpio))
return PTR_ERR(gpio);
if (gpio) {
/* set up GPIO */
}
While at it, device-managed variants of these functions are also
provided.

This commit adds the SMP support for Armada 375 and Armada 38x. It

* A different method to set the secondary CPU boot address
* An Armada 375 specific workaround needed for the early Z1 stepping,
added by the following patch.
Other than that, the patch is fairly straightforward and adds the
usual platsmp and headsmp code, defining the smp_operations structure
