- Samsung s2mps11
- Wolfson Microelectronics wm5102 and wm5110
- Marvell 88PM800 and 88PM805

We also have our regular driver improvements:
- Device tree and IRQ domain support for STE AB8500
- Regmap and devm_* API conversion for TI tps6586x
- Device tree support for Samsung max77686
- devm_* API conversion for STE AB3100
Besides that, quite a lot of fixing and cleanup for mc13xxx, tps65910,
tps65090, da9052 and twl-core."
Fix up mostly trivial conflicts, with the exception of
drivers/usb/host/ehci-omap.c in particular, which had some
re-organization of the reset sequence (commit 1a49e2ac96: "EHCI:
centralize controller initialization") that clashed with commit
2761a63945 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix
issues").
In particular, commit 2761a63945 moved the usb_add_hcd() to the
*middle* of the reset sequence, which clashes fairly badly with the
reset sequence re-organization (although it could have been done inside
the new omap_ehci_init() function).
I left that part of commit 2761a63945 just undone.

- This is inline with the mfd drivers implementation.
- This will move the related gpio support to gpio driver

This will be easy the maintenance and enhancement is
anything done for gpio.
- The gpio functionality can be selected through config

Pull MIPS updates from Ralf Baechle:
"The whole series has been sitting in -next for quite a while with no
complaints. The last change to the series was before the weekend the
removal of an SPI patch which Grant - even though previously acked by
himself - appeared to raise objections. So I removed it until the
situation is clarified. Other than that all the patches have the acks
from their respective maintainers, all MIPS and x86 defconfigs are
building fine and I'm not aware of any problems introduced by this
series.
Among the key features for this patch series is a sizable patchset for
Lantiq which among other things introduces support for Lantiq's
flagship product, the FALCON SOC. It also means that the opensource
developers behind this patchset have overtaken Lantiq's competing
inhouse development team that was working behind closed doors.
Less noteworthy the ath79 patchset which adds support for a few more
chip variants, cleanups and fixes. Finally the usual dose of tweaking
of generic code."

This patch is V2 of the Emma Mobile GPIO driver. This
driver is designed to be reusable between multiple SoCs
that share the same basic building block, but so far it
has only been used on Emma Mobile EV2.
Each driver instance handles 32 GPIOs with individually
maskable IRQs. The driver operates on two I/O memory
ranges and the 32 GPIOs are hooked up to two interrupts.
In the case of Emma Mobile EV2 this GPIO building block
is used as main external interrupt controller hooking up
159 GPIOS as 159 interrupts via 5 driver instances and
10 interrupts to the GIC and the Cortex-A9 Dual.

Rather than requiring architectures that use gpiolib but don't have any
need to define anything custom to copy an asm/gpio.h provide a Kconfig
symbol which architectures must select in order to include gpio.h and
for other architectures just provide the trivial implementation directly.
This makes it much easier to do gpiolib updates and is also a step towards
making gpiolib APIs available on every architecture.
For architectures with existing boilerplate code leave a stub header in
place which warns on direct inclusion of asm/gpio.h and includes
linux/gpio.h to catch code that's doing this. Direct inclusion of
asm/gpio.h has long been deprecated.
