The irqdomain creation that is carried out in:
platform_msi_create_device_domain()
relies on the fwnode_handle interrupt controller token to associate the
interrupt controller with a specific irqdomain. Current code relies on
the OF layer to retrieve a fwnode_handle for the device representing the
interrupt controller from its device->of_node pointer. This makes
platform_msi_create_device_domain() DT specific whilst it really is not
because after the merge of commit f94277af03ea ("of/platform: Initialise
dev->fwnode appropriately") the fwnode_handle can easily be retrieved
from the dev->fwnode pointer in a firmware agnostic way.Update platform_msi_create_device_domain() to retrieve the interrupt
controller fwnode_handle from the dev->fwnode pointer so that it can
be used seamlessly in ACPI and DT systems.Signed-off-by: Hanjun Guo

With the introduction of its_pmsi_init_one(), support for ACPI
firmware interface can be plugged into the gicv3 ITS driver.Add code to scan the MADT table to get the ITS entry(ies), then use
the information to create the platform msi domain for devices
connected to it, mirroring the ITS PCI MSI code path.Signed-off-by: Hanjun Guo

By adding ACPI support for platform MSI, the gicv3 driver has to
provide code to retrieve the dev id through ACPI instead of device
tree bindings; given that its_pmsi_prepare() allows already to get
the dev id but it is OF dependent, factor OF related code out into
a single function to make its_pmsi_prepare() ready to be used with
other firmware interfaces.Signed-off-by: Hanjun Guo

The Moxa Art interrupt controller is very very likely just an instance
of the Faraday FTINTC010 interrupt controller from Faraday Technology.
An indication would be its close association with the FA526 ARM core
and the fact that the register layout is the same.The implementation in irq-moxart.c can probably be right off replaced
with the irq-ftintc010.c driver by adding a compatible string, selecting
this irqchip from the machine and run.As a bonus we have an irqchip driver supporting high/low and
rising/falling edges for the Moxa Art, and shared code with the Gemini
platform.Acked-by: Olof Johansson

The triggers in the driver were right for high level triggered
IRQs but the edge detection on edge triggered IRQs was wrong.
After studying a proper driver from Po-Yu Chuang I now know how
to handle these right, and we can properly implement low level
IRQs as well.The device trees for the Gemini had polarity switched around
so these have been fixed to conform to the right polarity as
well.Cc: Greentime Hu

The Gemini irqchip turns out to be a standard IP component from
Faraday Technology named FTINTC010 after some research and new
information.- Rename the driver and all symbols to reflect the new information.
- Add the new compatible string "faraday,ftintc010"
- Create a Kconfig symbol CONFIG_FARADAY_FTINTC010 so that SoCs
using this interrupt controller can easily select and reuse it
instead of hardwiring it to ARCH_GEMINII have created a separate patch to select the new Kconfig symbol
from the Gemini machine, which will be merged through the ARM
SoC tree.Cc: Greentime Hu

When we merged the Gemini interrupt controller it was not yet
discovered that this IP block is actually a standard Faraday
Technology interrupt controller.As the IP block will probably appear in other designs as well,
let's augment the DT bindings to reflect that it is first and
foremost a standard Faraday part with a function name (FTINTC010)
so that people reusing the IP easily find the driver they need.Sorry for the mistakes due to lack of information.

This workqueue is used by our storage target mode ULPs
via the new CQ API. Recent observations when working
with very high-end flash storage devices reveal that
UNBOUND workqueue threads can migrate between cpu cores
and even numa nodes (although some numa locality is accounted
for).While this attribute can be useful in some workloads,
it does not fit in very nicely with the normal
run-to-completion model we usually use in our target-mode
ULPs and the block-mq irqcpu affinity facilities.The whole block-mq concept is that the completion will
land on the same cpu where the submission was performed.
The fact that our submitter thread is migrating cpus
can break this locality.We assume that as a target mode ULP, we will serve multiple
initiators/clients and we can spread the load enough without
having to use unbound kworkers.Also, while we're at it, expose this workqueue via sysfs which
is harmless and can be useful for debug.Signed-off-by: Sagi Grimberg
