Required Properties:

- compatible: has to be "qca,<soctype>-cpu-intc", "qca,ar7100-misc-intc"

  as fallback

- compatible: has to be "qca,<soctype>-cpu-intc", "qca,ar7100-misc-intc" or

  "qca,<soctype>-cpu-intc", "qca,ar7240-misc-intc"

- reg: Base address and size of the controllers memory area

- interrupt-parent: phandle of the parent interrupt controller.

- interrupts: Interrupt specifier for the controllers interrupt.

- #interrupt-cells : Specifies the number of cells needed to encode interrupt

		     source, should be 1

Compatible fallback depends on the SoC. Use ar7100 for ar71xx and ar913x,

use ar7240 for all other SoCs.

Please refer to interrupts.txt in this directory for details of the common

Interrupt Controllers bindings used by client devices.

(alternatively, the runtime_suspend() callback will have to check if the

device should really be suspended and return -EAGAIN if that is not the case).

The runtime PM of PCI devices is disabled by default.  It is also blocked by

pci_pm_init() that runs the pm_runtime_forbid() helper function.  If a PCI

driver implements the runtime PM callbacks and intends to use the runtime PM

framework provided by the PM core and the PCI subsystem, it should enable this

feature by executing the pm_runtime_enable() helper function.  However, the

driver should not call the pm_runtime_allow() helper function unblocking

the runtime PM of the device.  Instead, it should allow user space or some

platform-specific code to do that (user space can do it via sysfs), although

The runtime PM of PCI devices is enabled by default by the PCI core.  PCI

device drivers do not need to enable it and should not attempt to do so.

However, it is blocked by pci_pm_init() that runs the pm_runtime_forbid()

helper function.  In addition to that, the runtime PM usage counter of

each PCI device is incremented by local_pci_probe() before executing the

probe callback provided by the device's driver.

If a PCI driver implements the runtime PM callbacks and intends to use the

runtime PM framework provided by the PM core and the PCI subsystem, it needs

to decrement the device's runtime PM usage counter in its probe callback

function.  If it doesn't do that, the counter will always be different from

zero for the device and it will never be runtime-suspended.  The simplest

way to do that is by calling pm_runtime_put_noidle(), but if the driver

wants to schedule an autosuspend right away, for example, it may call

pm_runtime_put_autosuspend() instead for this purpose.  Generally, it

just needs to call a function that decrements the devices usage counter

from its probe routine to make runtime PM work for the device.

It is important to remember that the driver's runtime_suspend() callback

may be executed right after the usage counter has been decremented, because

user space may already have cuased the pm_runtime_allow() helper function

unblocking the runtime PM of the device to run via sysfs, so the driver must

be prepared to cope with that.

The driver itself should not call pm_runtime_allow(), though.  Instead, it

should let user space or some platform-specific code do that (user space can

do it via sysfs as stated above), but it must be prepared to handle the

runtime PM of the device correctly as soon as pm_runtime_allow() is called

(which may happen at any time).  [It also is possible that user space causes

pm_runtime_allow() to be called via sysfs before the driver is loaded, so in

fact the driver has to be prepared to handle the runtime PM of the device as

soon as it calls pm_runtime_enable().]

(which may happen at any time, even before the driver is loaded).

When the driver's remove callback runs, it has to balance the decrementation

of the device's runtime PM usage counter at the probe time.  For this reason,

if it has decremented the counter in its probe callback, it must run

pm_runtime_get_noresume() in its remove callback.  [Since the core carries

out a runtime resume of the device and bumps up the device's usage counter

before running the driver's remove callback, the runtime PM of the device

is effectively disabled for the duration of the remove execution and all

runtime PM helper functions incrementing the device's usage counter are

then effectively equivalent to pm_runtime_get_noresume().]

The runtime PM framework works by processing requests to suspend or resume

devices, or to check if they are idle (in which cases it is reasonable to
