…/linusw/linux-pinctrl
Pull pin control changes from Linus Walleij:
- A large slew of improvements of the Genric pin configuration support,
and deployment in four different platforms: Rockchip, Super-H PFC,
ABx500 and TZ1090. Support BIAS_BUS_HOLD, get device tree parsing
and debugfs support into shape.- We also have device tree support with generic naming conventions for
the generic pin configuration.- Delete the unused and confusing direct pinconf API. Now state
transitions is *the* way to control pins and multiplexing.- New drivers for Rockchip, TZ1090, and TZ1090 PDC.
- Two pin control states related to power management are now handled in
the device core: "sleep" and "idle", removing a lot of boilerplate
code in drivers. We do not yet know if this is the final word for
pin PM, but it already make things a lot easier to handle.- Handle sparse GPIO ranges passing a list of disparate pins, and
utilize these in the new BayTrail (x86 Atom SoC) driver.- Make the sunxi (AllWinner) driver handle external interrupts.
- Make it possible for pinctrl-single to handle the case where several
pins are managed by a single register, and augment it to handle sleep
modes.- Cleanups and improvements for the abx500 drivers.
- Move Sirf pin control drivers to their own directory, support
save/restore of context and add support for the SiRFatlas6 SoC.- PMU muxing for the Dove pinctrl driver.
- Finalization and support for VF610 in the i.MX6 pinctrl driver.
- Smoothen out various Exynos rough edges.
- Generic cleanups of various kinds.

Pull ARM SoC driver specific changes from Arnd Bergmann:
"These changes are all driver specific and cross over between arm-soc
contents and some other subsystem, in these cases cpufreq, crypto,
dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have
these changes merged through arm-soc.As we proceed to untangle the dependencies between platform code and
driver code, the amount of changes in this category is fortunately
shrinking, for 3.11 we have 16 branches here and 101 non-merge
changesets, the majority of which are for the stedma40 dma engine
driver used in the ux500 platform. Cleaning up that code touches
multiple subsystems, but gets rid of the dependency in the end.The mailbox code moved out from mach-omap2 to drivers/mailbox is an
intermediate step and is still omap specific at the moment. Patches
exist to generalize the subsystem and add other drivers with the same
API, but those did not make it for 3.11."* tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (101 commits)

This driver adds support the Cortex-A9 based SoCs from Rockchip,
so at least the RK2928, RK3066 (a and b) and RK3188.
Earlier Rockchip SoCs seem to use similar mechanics for gpio
handling so should be supportable with relative small changes.
Pull handling on the rk3188 is currently a stub, due to it being
a bit different to the earlier SoCs.Pinmuxing as well as gpio (and interrupt-) handling tested on
a rk3066a based machine.Signed-off-by: Heiko Stuebner

From Stephen Warren:
ARM: tegra: device tree updatesThis branch contains all device tree updates for Tegra boards.
The changes are:
* Converted all DT files to use the C pre-processor, to support the use
of named constants. This included use of defines for GPIO, IRQ, and
clock constants.
* Enabling new features such as:
- SPI on Dalmore.
- Audio on Dalmore and Beaver.
- gpio-leds on Beaver.
- Power-supply/batter linkage on Dalmore.
* A minor fix to the RAM size node on Beaver.It is based on previous pull request tegra-for-3.11-deps-for-usb

DMA-cell content is a concatenation of several values. In order to keep this
stuff human readable, macros are introduced.The values for the FIFO configuration are not the same as the ones used in the
configuration register in order to keep backward compatibility. Most devices
use the half FIFO configuration but USART ones have to use the ASAP
configuration. This parameter was not initially planed to be into the at91 dma
dt binding. The third cell will be used to store this parameter, it will
become a concatenation of the FIFO configuration and of the peripheral ID. In
order to keep backward compatibility i.e. FIFO configuration is equal to 0, we
have to perform a translation since the value to put in the register to set
half FIFO is 1.Acked-by: Arnd Bergmann
