"This is the bulk of pin control changes for the v5.11 kernel.
Drivers, drivers and drivers. Not a single core change.
Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot

As part of the modularization attempt, I applied one patch affecting
the firmware subsystem as a functional (not syntactic/semantic)

bummer. It will come in later, through that subsystem, I guess.

Add initial pinctrl driver to support pin configuration for
LPASS (Low Power Audio SubSystem) LPI (Low Power Island) pinctrl
on SM8250.
This IP is an additional pin control block for Audio Pins on top the
existing SoC Top level pin-controller.
Hardware setup looks like:
TLMM GPIO[146 - 159] --> LPASS LPI GPIO [0 - 13]
This pin controller has some similarities compared to Top level
msm SoC Pin controller like 'each pin belongs to a single group'
and so on. However this one is intended to control only audio
pins in particular, which can not be configured/touched by the
Top level SoC pin controller except setting them as gpios.
Apart from this, slew rate is also available in this block for
certain pins which are connected to SLIMbus or SoundWire Bus.

Tweaks to allow pinctrl-msm code to be loadable as a module.
This is needed in order to support having the qcom-scm driver,
which pinctrl-msm calls into, configured as a module.
This requires that we tweak Kconfigs selecting PINCTRL_MSM to
also depend on QCOM_SCM || QCOM_SCM=n so that we match the
module setting of QCOM_SCM.

This patch reworks PINCTRL_MSM to be a visible option, and
instead of having the various SoC specific drivers select
PINCTRL_MSM, this switches those configs to depend on
PINCTRL_MSM.
This is useful, as it will be needed in order to cleanly support
having the qcom-scm driver, which pinctrl-msm calls into,
configured as a module. Without this change, we would eventually
have to add dependency lines to every config that selects
PINCTRL_MSM, and that would becomes a maintenance headache.
We also add PINCTRL_MSM to the arm64 defconfig to avoid
surprises as otherwise PINCTRL_MSM/IPQ* options previously
enabled, will be off.

When GPIOs that are routed to PDC are used as output they can still latch
the IRQ pending at GIC. As a result the spurious IRQ was handled when the
client driver change the direction to input to starts using it as IRQ.
Currently such erroneous latched IRQ are cleared with .irq_enable callback
however if the driver continue to use GPIO as interrupt and invokes
disable_irq() followed by enable_irq() then everytime during enable_irq()
previously latched interrupt gets cleared.
This can make edge IRQs not seen after enable_irq() if they had arrived
after the driver has invoked disable_irq() and were pending at GIC.
Move clearing erroneous IRQ to .irq_request_resources callback as this is
the place where GPIO direction is changed as input and its locked as IRQ.
While at this add a missing check to invoke msm_gpio_irq_clear_unmask()
from .irq_enable callback only when GPIO is not routed to PDC.

msmgpio irqchip was not using return value of irq_set_irq_wake() callback
since previously GIC-v3 irqchip neither had IRQCHIP_SKIP_SET_WAKE flag nor
it implemented .irq_set_wake callback. This lead to irq_set_irq_wake()
return error -ENXIO.
However from 'commit 4110b5cbb0 ("irqchip/gic-v3: Allow interrupt to be
configured as wake-up sources")' GIC irqchip has IRQCHIP_SKIP_SET_WAKE
flag.
Use return value from irq_set_irq_wake() and irq_chip_set_wake_parent()
instead of always returning success.

Both IRQCHIP_SET_TYPE_MASKED and IRQCHIP_MASK_ON_SUSPEND flags are already
set for msmgpio's parent PDC irqchip but GPIO interrupts do not get masked
during suspend or during setting irq type since genirq checks irqchip flag
of msmgpio irqchip which forwards these calls to its parent PDC irqchip.
Add irqchip specific flags for msmgpio irqchip to mask non wakeirqs during
suspend and mask before setting irq type. Masking before changing type make
sures any spurious interrupt is not detected during this operation.

Core changes:
- The GPIO patch "gpiolib: Introduce
for_each_requested_gpio_in_range() macro" was put in an
immutable branch and merged into the pinctrl tree as well.
We see these changes also here.
- Improved debug output for pins used as GPIO.
New drivers:
- Ocelot Sparx5 SoC driver.
- Intel Emmitsburg SoC subdriver.
- Intel Tiger Lake-H SoC subdriver.
- Qualcomm PM660 SoC subdriver.
- Renesas SH-PFC R8A774E1 subdriver.
Driver improvements:
- Linear improvement and cleanups of the Intel drivers for
Cherryview, Lynxpoint, Baytrail etc. Improved locking among
other things.
- Renesas SH-PFC has added support for RPC pins, groups, and
functions to r8a77970 and r8a77980.
- The newere Freescale (now NXP) i.MX8 pin controllers have
been modularized. This is driven by the Google Android
GKI initiative I think.
- Open drain support for pins on the Qualcomm IPQ4019.
- The Ingenic driver can handle both edges IRQ detection.
- A big slew of documentation fixes all over the place.
- A few irqchip template conversions by yours truly.

Depending on how you look at it, you can either say that:
a) There is a PDC hardware issue (with the specific IP rev that exists
on sc7180) that causes the PDC not to work properly when configured
to handle dual edges.
b) The dual edge feature of the PDC hardware was only added in later
HW revisions and thus isn't in all hardware.
Regardless of how you look at it, let's work around the lack of dual
edge support by only ever letting our parent see requests for single
edge interrupts on affected hardware.
NOTE: it's possible that a driver requesting a dual edge interrupt
might get several edges coalesced into a single IRQ. For instance if
a line starts low and then goes high and low again, the driver that
requested the IRQ is not guaranteed to be called twice. However, it
is guaranteed that once the driver's interrupt handler starts running
its first instruction that any new edges coming in will cause the
interrupt to fire again. This is relatively commonplace for dual-edge
gpio interrupts (many gpio controllers require software to emulate
dual edge with single edge) so client drivers should be setup to
handle it.

The hierarchical parts of MSM pinctrl/GPIO is only
used when the device tree has a "wakeup-parent" as
a phandle, but the .irq_eoi is anyway assigned leading
to semantic problems on elder Qualcomm chipsets.
When the drivers/mfd/qcom-pm8xxx.c driver calls
chained_irq_exit() that call will in turn call chip->irq_eoi()
which is set to irq_chip_eoi_parent() by default on a
hierachical IRQ chip, and the parent is pinctrl-msm.c
so that will in turn unconditionally call
irq_chip_eoi_parent() again, but its parent is invalid
so we get the following crash:
Unnable to handle kernel NULL pointer dereference at
virtual address 00000010
pgd = (ptrval)
[00000010] *pgd=00000000
Internal error: Oops: 5 [#1] PREEMPT SMP ARM
(...)
PC is at irq_chip_eoi_parent+0x4/0x10
LR is at pm8xxx_irq_handler+0x1b4/0x2d8
If we solve this crash by avoiding to call up to
irq_chip_eoi_parent(), the machine will hang and get
reset by the watchdog, because of semantic issues,
probably inside irq_chip.
As a solution, just assign the .irq_eoi conditionally if
we are actually using a wakeup parent.

Use newly added GPIO defines GPIO_LINE_DIRECTION_IN and
GPIO_LINE_DIRECTION_OUT instead of using hard-coded 1 and 0.
Main benefit is to make it easier to see which values mean IN and which
OUT. As a side effect this helps GPIO framework to change the direction
defines to something else if ever needed.
Please note that return value from get_direction call on
pinctrl-axp209 driver was changed. Previously pinctrl-axp209 might have
returned value 2 for direction INPUT.

Core changes:
- Dropped the chained IRQ setup callback into GPIOLIB as we
got rid of the last users of that in this changeset.
New drivers:
- New driver for Ingenic X1830.
- New driver for Freescale i.MX8MP.
Driver enhancements:
- Fix all remaining Intel drivers to pass their IRQ chips
along with the GPIO chips.
- Intel Baytrail allocates its irqchip dynamically.
- Intel Lynxpoint is thoroughly rewritten and modernized.
- Aspeed AST2600 pin muxing and configuration is much
improved.
- Qualcomm SC7180 functions are updated and wakeup interrupt
map is provided.
- A whole slew of Renesas SH-PFC cleanups and improvements.
- Fix up the Intel DT bindings to use the generic YAML
DT bindings schema. (A first user of this.)

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes, nothing too exciting about
this.
Some changes hit arch/sh and arch/arm but are well isolated and
acknowledged by the respective arch maintainers.
Core changes:
- Dropped the chained IRQ setup callback into GPIOLIB as we got rid
of the last users of that in this changeset.
New drivers:
- New driver for Ingenic X1830.
- New driver for Freescale i.MX8MP.

* tag 'pinctrl-v5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (99 commits)
pinctrl: madera: Remove extra blank line

pinctrl: mvebu: armada-37xx: use use platform api
gpio: Drop the chained IRQ handler assign function
pinctrl: freescale: Add i.MX8MP pinctrl driver support

pinctrl: tigerlake: Tiger Lake uses _HID enumeration
pinctrl: sunrisepoint: Add Coffee Lake-S ACPI ID
pinctrl: iproc: Use platform_get_irq_optional() to avoid error message
pinctrl: dt-bindings: Fix some errors in the lgm and pinmux schema
pinctrl: intel: Pass irqchip when adding gpiochip
pinctrl: intel: Add GPIO <-> pin mapping ranges via callback
pinctrl: baytrail: Replace WARN with dev_info_once when setting direct-irq pin to output
pinctrl: baytrail: Do not clear IRQ flags on direct-irq enabled pins
pinctrl: sunrisepoint: Add missing Interrupt Status register offset
pinctrl: sh-pfc: Split R-Car H3 support in two independent drivers
pinctrl: artpec6: fix __iomem on reg in set
pinctrl: ingenic: Use devm_platform_ioremap_resource()
pinctrl: ingenic: Factorize irq_set_type function
pinctrl: ingenic: Remove duplicated ingenic_chip_info structures
...
Some gpio's parent irqdomain may not use the struct irq_fwspec as
argument, such as msi irqdomain. So rename the callback
populate_parent_fwspec() to populate_parent_alloc_arg() and make it
allocate and populate the specific struct which is needed by the
parent irqdomain.

on sc7180 we have cases where multiple functions from the same
qup instance share the same pin. This is true for qup02/04/11 and qup13.
Add new function names to distinguish which qup function to use.
The device tree files for this platform haven't landed in mainline yet,
so there aren't any users upstream who should break with this change
in function names, however, anyone using the devicetree files that were
posted on the lists and using these specific function names will need
to update their changes.
