Joachim Eastwood 27dc2fb18f doc: dt: add documentation for lpc1850-rgu reset driver
Add device tree binding documentation for the Reset Generation Unit
(RGU) found on NXP LPC18xx and LPC43xx devies.

This documentation also includes a table which shows the RGU reset
number and the connected peripheral.

Philipp Zabel efdf5aa8f1 ARM: STi: DT: Move reset controller constants into common location
By popular vote, the DT binding includes for reset controllers are located
in include/dt-bindings/reset/. Move the STi reset constants in there, too,
to avoid confusion.

Antoine Tenart 185cff3d66 Documentation: bindings: move the Berlin reset documentation
The Berlin reset documentation was part of the Marvell Berlin SoC
documentation because the Berlin reset configuration was inside the chip
controller. With the recent rework of the chip and system controller
handling (now an MFD driver registers all sub-devices of the two soc and
system controller nodes and each device has its own sub-node), the
documentation of the Berlin reset driver can be moved to the generic
reset documentation directory.

This patchset attempts to standardize the naming of dt-bindings
documents based on the Broadcom vendor prefix of brcm.

Although there are no guidelines currently present for how to name
the dt-bindings document the "vendor,binding.txt" style is in use by
some of the other vendors.

Linus Torvalds a727eaf64f ARM: SoC driver changes
SoC-near driver changes that we're merging through our tree. Mostly
 because they depend on other changes we have staged, but in some cases
 because the driver maintainers preferred that we did it this way.
 
 This contains a largeish cleanup series of the omap_l3_noc bus driver,
 cpuidle rework for Exynos, some reset driver conversions and a long
 branch of TI EDMA fixes and cleanups, with more to come next release.
 
 The TI EDMA cleanups is a shared branch with the dmaengine tree, with
 a handful of Davinci-specific fixes on top.
 
 After discussion at last year's KS (and some more on the mailing lists),
 we are here adding a drivers/soc directory. The purpose of this is
 to keep per-vendor shared code that's needed by different drivers but
 that doesn't fit into the MFD (nor drivers/platform) model. We expect
 to keep merging contents for this hierarchy through arm-soc so we can
 keep an eye on what the vendors keep adding here and not making it a
 free-for-all to shove in crazy stuff.

Linus Torvalds f83ccb9358 ARM: SoC: device tree changes
A large part of the arm-soc patches are nowadays DT changes, adding support
 for new SoCs, boards and devices without changing kernel source. The plan
 is still to move the devicetree files out of the kernel tree and reduce
 the amount of churn going on here, but we keep finding reasons to delay
 doing that.
 
 Changes are really all over the place, with little sticking out particularly.
 We have contributions from a total of 116 people in this branch.
 
 Unfortunately, the size of this branch also causes a significant number
 of conflicts at the moment, typically when subsystem maintainers merge
 patches that change the driver at the same time as the dts files. In
 most cases this could be avoided because the dts changes are supposed
 to be compatible in both ways, and we are asking everyone to send ARM
 dts changes through our tree only.

Stephen Warren 4e11f848c6 dt: describe base reset signal binding
This binding is intended to represent the hardware reset signals present
internally in most IC (SoC, FPGA, ...) designs.
It consists of a binding for a reset controller device (provider), and a
pair of properties, "resets" and "reset-names", to link a device node
(consumer) to its reset controller via phandle, similarly to the clock
and interrupt bindings.

The reset controller has all information necessary to reset the consumer
device. That could be provided via device tree, or it could be implemented
in hardware.
The aim is to enable device drivers to request a framework API to issue a
reset simply by providing their struct device pointer as the most common
case.
