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.

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.

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.

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

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.
