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
Currently msi-parent is used by a few bindings to describe the
relationship between a PCI root complex and a single MSI controller, but
this property does not have a generic binding document.
Additionally, msi-parent is insufficient to describe more complex
relationships between MSI controllers
The existing IOMMU bindings are able to specify the relationship between
masters and IOMMUs, but they are insufficient for describing the general
case of hotpluggable busses such as PCI where the set of masters is not
known until runtime, and the relationship between masters and IOMMUs is

On nohz full early days, idle dynticks and full dynticks weren't well
integrated and we couldn't risk full dynticks calls on idle without
risking messing up tick idle statistics. This is why we prevented such
thing to happen.
Nowadays full dynticks and idle dynticks are better integrated and

v7:

- update the DT bindings documentation accordingly.
v6:

the first available
Instead of providing asynchronous checks for the nohz subsystem to verify
sched tick dependency, migrate sched to the new mask.
The easiest is to recycle the current asynchronous tick dependency check
which verifies the class of the current task and its requirements for
periodic preemption
Instead of providing asynchronous checks for the nohz subsystem to verify
posix cpu timers tick dependency, migrate the latter to the new mask.
In order to keep track of the running timers and expose the tick
dependency accordingly, we must probe the timers queuing and dequeuing
on threads and
The task switch check was there to evaluate task level tick dependencies.
Now all of them have been converted to the new CPU or system wide tick
dependency masks that are toggled by the concerned subsystems. We can
safely remove it.

Restart the tick when necessary from the irq exit path. It makes nohz
full more flexible, simplify the related IPIs and doesn't bring
significant overhead on irq exit.
