The original version can only used by old Loongson-3 which only use 4
groups of HT vectors. Now Loongson-3A R4 can use 8 groups, so improve
the driver to support all 8 groups.

In gc->mask_cache bits, 1 means enabled and 0 means disabled, but in the
loongson-liointc driver mask_cache is misused by reverting its meaning.

When the system is suspended, we can explicitly disable clock to save
power. To achieve this, we need save registers' state since it could be
lost after power off.
Implement power management which will:
- Turn the clock off after probing
- Disable clock and save registers' state on system suspend, as
well as enable clock and restore registers' state on resume
- Rely on the Power Domain framework to shutdown the intmux
power domain
Without CONFIG_PM, the clock is always on after probe stage.

It turned out that we're allocating memory using GFP_KERNEL (may sleep)

thing may happen if we're playing on a system with more than a single

EXTI lines are mainly used to wake-up system from CStop low power mode.
Currently, if a device wants to use a EXTI (direct) line as wakeup line,
it has to declare 2 interrupts:
- one for EXTI used to wake-up system (with dedicated_wake_irq api).
- one for GIC used to get the wake up reason inside the concerned IP.
This split is not really needed as each EXTI line is actually "linked " to
a GIC. So to avoid this useless double interrupt management in each
wake-up driver, this patch lets the STM32 EXTI driver abstract it by
mapping each EXTI line to his corresponding GIC.

Compiling an irqchip driver as a platform driver needs to bunch of
things to be done right:
- Making sure the parent domain is initialized first
- Making sure the device can't be unbound from sysfs
- Disallowing module unload if it's built as a module
- Finding the parent node
- Etc.
Instead of trying to make sure all future irqchip platform drivers get
this right, provide boilerplate macros that take care of all of this.
An example use would look something like this. Where acme_foo_init and
acme_bar_init are similar to what would be passed to IRQCHIP_DECLARE.
IRQCHIP_PLATFORM_DRIVER_BEGIN(acme_irq)
IRQCHIP_MATCH("acme,foo", acme_foo_init)
IRQCHIP_MATCH("acme,bar", acme_bar_init)
IRQCHIP_PLATFORM_DRIVER_END(acme_irq)

The GICv4.1 spec tells us that it's CONSTRAINED UNPREDICTABLE to issue a
register-based invalidation operation for a vPEID not mapped to that RD,
or another RD within the same CommonLPIAff group.
To follow this rule, commit f3a059219bc7 ("irqchip/gic-v4.1: Ensure mutual
exclusion between vPE affinity change and RD access") tried to address the
race between the RD accesses and the vPE affinity change, but somehow
forgot to take GICR_INVALLR into account. Let's take the vpe_lock before
evaluating vpe->col_idx to fix it.

In an effort to enable -Wcast-function-type in the top-level Makefile to
support Control Flow Integrity builds, there are the need to remove all
the function callback casts.
To do this, modify the IRQCHIP_ACPI_DECLARE macro to use the new defined
macro ACPI_DECLARE_SUBTABLE_PROBE_ENTRY instead of the macro
ACPI_DECLARE_PROBE_ENTRY. This is necessary to be able to initialize the
the acpi_probe_entry struct using the probe_subtbl field instead of the
probe_table field and avoid function cast mismatches.
Also, modify the prototype of the functions used by the invocation of the
IRQCHIP_ACPI_DECLARE macro to match all the parameters.

Use the correct the function name in the documentation for
"pcs_parse_one_pinctrl_entry()".
"smux_parse_one_pinctrl_entry()" appears to be an artifact from the
development of a prior patch series ("simple pinmux driver") which
transformed into pinctrl-single.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"A feature (papr_scm health retrieval) and a fix (sysfs attribute
visibility) for v5.8.
Vaibhav explains in the merge commit below why missing v5.8 would be
painful and I agreed to try a -rc2 pull because only cosmetics kept
this out of -rc1 and his initial versions were posted in more than
enough time for v5.8 consideration:
'These patches are tied to specific features that were committed to
customers in upcoming distros releases (RHEL and SLES) whose
time-lines are tied to 5.8 kernel release.
Being able to track the health of an nvdimm is critical for our
customers that are running workloads leveraging papr-scm nvdimms.
Missing the 5.8 kernel would mean missing the distro timelines and
shifting forward the availability of this feature in distro kernels
by at least 6 months'
Summary:
- Fix the visibility of the region 'align' attribute.
The new unit tests for region alignment handling caught a corner
case where the alignment cannot be specified if the region is
converted from static to dynamic provisioning at runtime.
- Add support for device health retrieval for the persistent memory
supported by the papr_scm driver.
This includes both the standard sysfs "health flags" that the nfit
persistent memory driver publishes and a mechanism for the ndctl
tool to retrieve a health-command payload"

leak in case of error in 'imx_pinctrl_probe()'"
This reverts commit ba403242615c2c99e27af7984b1650771a2cc2c9.
After commit 26d8cde5260b ("pinctrl: freescale: imx: add shared
input select reg support"). i.MX7D has two iomux controllers
iomuxc and iomuxc-lpsr which share select_input register for
daisy chain settings.
If use 'devm_of_iomap()', when probe the iomuxc-lpsr, will call
devm_request_mem_region() for the region <0x30330000-0x3033ffff>
for the first time. Then, next time when probe the iomuxc, API
devm_platform_ioremap_resource() will also use the API
devm_request_mem_region() for the share region <0x30330000-0x3033ffff>
again, then cause issue, log like below:
[ 0.179561] imx7d-pinctrl 302c0000.iomuxc-lpsr: initialized IMX pinctrl driver
[ 0.191742] imx7d-pinctrl 30330000.pinctrl: can't request region for resource [mem 0x30330000-0x3033ffff]
