f7fafd083c leds: leds-ns2: move LED modes mapping outside of the driver
On the board n090401 (Seagate NAS 4-Bay), the LED mode mapping (GPIO
values to LED mode) is different from the one used on other boards
supported by the leds-ns2 driver.

With this patch the hardcoded mapping is removed from leds-ns2. Now,
it must be defined either in the platform data (if an old-fashion board
setup file is used) or in the DT node. In order to allow the later, this
patch also introduces a modes-map property for the leds-ns2 DT binding.

3fffd12839 i2c: allow specifying separate wakeup interrupt in device tree
Instead of having each i2c driver individually parse device tree data in
case it or platform supports separate wakeup interrupt, and handle
enabling and disabling wakeup interrupts in their power management
routines, let's have i2c core do that for us.

Platforms wishing to specify separate wakeup interrupt for the device
should use named interrupt syntax in their DTSes:

	interrupt-parent = <&intc1>;
	interrupts = <5 0>, <6 0>;
	interrupt-names = "irq", "wakeup";

This patch is inspired by work done by Vignesh R <vigneshr@ti.com> for
pixcir_i2c_ts driver.

Note that the original code tried to preserve any existing wakeup
settings from userspace but was not quite right in that regard:
it would preserve wakeup flag set by userspace upon driver rebinding;
but it would re-arm the wakeup flag if it was disabled by userspace.

We think that resetting the flag upon re-binding the driver is proper
behavior as the driver is responsible for setting up and handling
wakeups.

126b16e2ad Docs: dt: add generic MSI bindings
Currently msi-parent is used in a couple of drivers despite being fairly
underspecified. This patch adds a generic binding for MSIs (including
the existing msi-parent property) enabling the description of platform
devices capable of using MSIs.

While MSIs are primarily distinguished by doorbell and payload, some MSI
controllers (e.g. the GICv3 ITS) also use side-band information
accompanying the write to identify the master which originated the MSI,
to allow for sandboxing. This sideband information is non-probeable and
needs to be described in the DT. Other MSI controllers may have
additional configuration details which need to be described per-master.

This patch adds a generic msi-parent binding document, extending the
de-facto standard with a new (optional) #msi-cells which can be used to
express any per-master configuration and/or sideband data. This is
sufficient to describe non-hotpluggable devices.

For busses where sideband data may be derived from some bus-specific
master ID scheme, other properties will be required to describe the
mapping.

62f4771198 clk: versatile: Switch to assigned clock parents
We're removing struct clk from the clk provider API. This code is
calling the consumer APIs to change the parent to a 1 MHz fixed
rate clock for each of the clocks that the driver provides. Move
to using the assigned-clock-parents DT property for this instead.
Because this is an ABI break, detect if the property is missing
and fall back to setting the parent explicitly before the clocks
are registered.

The Maxim MAX77686 PMIC is a multi-function device with regulators,
clocks and a RTC. The DT bindings for the clocks are in a separate
file but the bindings for the regulators are inside the mfd part.

To make it consistent with the clocks portion of the binding and
because is more natural to look for regulator bindings under the
bindings/regulator sub-directory, split the regulator portion of
the DT binding and add it as a separate file.

43bcad2bb4 devicetree: Add bindings documentation for Analog Devices AXI-DMAC
Add the devicetree descriptor for the Analog Devices AXI-DMAC DMA
controller. This is a soft peripheral used in FPGAs and the bindings
describe how it is connected to the system (clock, interrupt, memory map)
as well as the configuration options that were used when the peripheral was
instantiated.

4b226fbde6 dt: snps,dw-apb-ssi: Document new I/O data register width property
This change documents a new property for the snps,dw-apb-ssi device,
allowing an implementer to specify either four byte or two bytes
access to the SPI controller data register.

This supports a change that unbreaks this driver on picoXcell
platforms.

f4be3c67ed ARM: tegra: Devicetree changes for v4.3-rc1
Enables CPU frequency scaling on Jetson TK1 and enables the GK20A GPU on
 Venice2 and Jetson TK1. This also enables support for the PMU hardware
 found on Tegra124, which among other things, can be used for performance
 measurements.

a493f339a8 irqchip/bcm2835: Add support for being used as a second level controller
The BCM2836 (Raspberry Pi 2) uses two levels of interrupt handling
with the CPU-local interrupts being the root, so we need to register
ours as chained off of the CPU's local interrupt.
