Pull pin control changes from Linus Walleij:
"This is the bulk of pin control changes for the v3.16 development
cycle:
- Antoine Tenart made the get_group_pins() vtable entry optional.
- Antoine also provides an entirely new driver for the Marvell Berlin
SoC. This is unrelated to the existing MVEBU hardware driver and
warrants its own separate driver.
- reflected from the GPIO subsystem there is a number of refactorings
to make pin control drivers with gpiochips use the new gpiolib
irqchip helpers. The following drivers were converted to use the
new infrastructure:
* ST Microelectronics STiH416 and friends
* The Atmel AT91
* The CSR SiRF (Prima2)
* The Qualcomm MSM series
- massive improvements in the Qualcomm MSM driver from Bjorn
Andersson, Andy Gross and Kumar Gala. Among those new support for
the IPQ8064 and MSM8x74 SoC variants.
- support for the Freescale i.MX6 SoloX SoC variant.
- massive improvements in the Allwinner sunxi driver from Boris
Brezillon, Maxime Ripard and Chen-Yu Tsai.
- Renesas PFC updates from Laurent Pinchart, Kuninori Morimoto,
Wolfram Sang and Magnus Damm.
- Cleanups and refactorings of the nVidia Tegra driver from Stepgen
Warren.
- the Exynos driver now supports the Exynos3250 SoC.
- Intel BayTrail updates from Jin Yao, Mika Westerberg.
- the MVEBU driver now supports the Orion5x SoC variants, which is
part of the effort of getting rid of the old Marvell kludges in
arch/arm/mach-orion5x
- Rockchip driver updates from Heiko Stuebner.
- a ton of cleanups and janitorial patches from Axel Lin.
- some minor fixes and improvements here and there"

In the multiplatform kernel case the IRQs associated with the PFC GPIOs
are specified through DT. The pinmux_irq irq field is thus ignored by
the code, and doesn't need to be set.
This will allow removing the mach/irq.h include from pfc-*.c files that
was required for the irq_pin() macro used to initialize the irq field.

"This has been queued and tested for a while. Lots of action here,
like in the GPIO tree, embedded stuff like this is really hot now it
seems. Details in the signed tag. I'm especially happy about the
Qualcomm driver as it is used in such a huge subset of mobile handsets
out there, and these platforms in general need better upstream support

subdriver.
- New driver for the Broadcom Capri BCM281xx SoC.
- New subdriver for the imx25 pin controller.
- New subdriver for the Tegra124 pin controller.
- Lock GPIO lines as IRQs for select combined pin control and GPIO
drivers for baytrail and sirf.
- Some semi-big refactorings and extenstions to the sirf driver.
- Lots of patching, cleanup and fixing in the Renesas "PFC" driver
and associated subdrivers as usual. It is settling down a little
bit now it seems.

On non-DT platforms IRQ controllers associated with the GPIOs have a
fixed IRQ base value known at compile time. The sh-pfc driver translates
GPIO number to IRQ numbers using a hardcoded table. This mechanism
breaks on DT platforms, as the IRQ base values are dynamic in that case.
Fix this by specifying IRQs associated with GPIOs in IRQ resources,
populated automatically from the device tree. When IRQ resources are
specified the driver requires one IRQ resource per GPIO able to generate
an interrupt, and uses the translation table to compute the IRQ resource
offset instead of the IRQ number.

This reorganizes and renames VIN0 data pin groups to cover

pin groups, one per each configuration. Most of the groups
share the same pin/mux array. Only the 18-bit configuration
needs a separate pin/mux array since in combines interleaved
data pins.

group for the DU, move the cde_disp mux array right after the
