Account for more than only 23 GPIOs in LPASS Low Power Island pinctrl
generic driver. The previous value 23 was chosen to satisfy existing
SoC-specific drivers. However SM4250 LPI pinctrl uses more than 23 GPIOs
and its probe routine fails on:

return -EINVAL;

The PDC was hooked up as a wakeup parent in the DTS in
commit 71f080633d1e ("arm64: dts: qcom: sdm670: Hook up PDC as
wakeup-parent of TLMM"), but the wakeirq mapping was not defined so it
had no effect. Add the mapping for wakeup interrupts on the PDC to their
corresponding pins.
Configuring a pin IRQ as dual-edge would break it unless the
wakeirq_dual_edge_errata flag is set.

The SPMI GPIO driver assumes that the parent device is an SPMI device
and accesses random data when backcasting the parent struct device
pointer for non-SPMI devices.
Fortunately this does not seem to cause any issues currently when the
parent device is an I2C client like the PM8008, but this could change if
the structures are reorganised (e.g. using structure randomisation).
Notably the interrupt implementation is also broken for non-SPMI devices.
Also note that the two GPIO pins on PM8008 are used for interrupts and
reset so their practical use should be limited.
Drop the broken GPIO support for PM8008 for now.

The pinconf-groups debugfs file dumps each valid configuration item of
all pin groups. Some platforms and devices may have pin groups which
cannot be accessed, according to commit 691bf5d5a7bf ("pinctrl: qcom:
Don't allow protected pins to be requested"). Fail for each
configuration item of an invalid pin group by checking the GPIO chip's
valid mask.
The validity of the pin group cannot be checked in the generic pinconf
dump (function "pinconf_generic_dump_one"), as it does not directly
interact with the gpiochip or the pinmux callbacks (which would give it
access to the request callback). Instead, an entry contains the ID and
name of the pingroup with no properties when all items fail.

Existing Qualcomm SoCs have the LPASS pin controller slew rate control
in separate register, however this will change with upcoming Qualcomm
SoCs. The slew rate will be part of the main register for pin

New platforms uses a new set of bits to control the wakeirq
delivery to the PDC block.
The intr_wakeup_present_bit indicates if the GPIO supports
wakeirq and intr_wakeup_enable_bit enables wakeirq delivery
to the PDC block.
While the name seems to imply this only enables wakeup events,
it is required to allow interrupts events to the PDC block.
Enable this bit in the irq resource request/free if:
- gpio is in wakeirq map
- has the intr_wakeup_present_bit
- the intr_wakeup_enable_bit is set

Add driver for the pin controller in Low Power Audio SubSystem (LPASS)
of Qualcomm SM8650 SoC.
Notable differences against SM8550 LPASS pin controller:
1. Additional address space for slew rate thus driver uses
LPI_FLAG_SLEW_RATE_SAME_REG and sets slew rate via different
register.
2. Two new pin mux functions: qca_swr_clk and qca_swr_data

The Qualcomm LPASS LPI pin controller driver uses one lock for guarding
Read-Modify-Write code for slew rate registers. However the pin
configuration and muxing registers have exactly the same RMW code but
are not protected.
Pin controller framework does not provide locking here, thus it is
possible to trigger simultaneous change of pin configuration registers
resulting in non-atomic changes.
Protect from concurrent access by re-using the same lock used to cover
the slew rate register. Using the same lock instead of adding second
one will make more sense, once we add support for newer Qualcomm SoC,
where slew rate is configured in the same register as pin
configuration/muxing.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
To convert all those qcom pinctrl drivers, make msm_pinctrl_remove()
return void (instead of zero) and use .remove_new in all drivers.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

Pull pin control updates from Linus Walleij:
"We have some patches to DTS[I] files in arm and arm64 as well, that
were merged here as DT headers were being changed.
The most interesting stuff is the Intel Tangier chip support and
AMLogic C3 in my opinion.
No core changes this time.
Drivers:
- Intel Tangier SoC pin control support
- AMLogic C3 SoC pin control support
- Texas Instruments AM654 SoC pin control support
- Qualcomm SM8350 and SM6115 LPASS (Low Power Audio Sub-System) pin
control support
- Qualcomm PMX75 and PM7550BA (Power Management) pin control support
- Qualcomm PMC8180 and PMC8180C (Power Management) pin control
support
- DROP the Oxnas driver as there is not enough of community interest
to keep carrying this ARM(11) port
Enhancements:
- Bias control in the MT7986 pin control driver
- Misc device tree binding enhancements such as the Broadcom 11351
being converted to YAML
- New macro: DEFINE_NOIRQ_DEV_PM_OPS() put to use
- Clean up some SPDX headers
- Handle non-unique devicetree subnode names in two Renesas drivers"

interrupt targets
SA8775 and newer target have added support for an increased number of
interrupt targets. To implement this change, the intr_target field, which
is used to configure the interrupt target in the interrupt configuration
register is increased from 3 bits to 4 bits.
In accordance to these updates, a new intr_target_width member is
introduced in msm_pingroup structure. This member stores the value of
width of intr_target field in the interrupt configuration register. This
value is used to dynamically calculate and generate mask for setting the
intr_target field. By default, this mask is set to 3 bit wide, to ensure
backward compatibility with the older targets.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

In menuconfig, some entries depending on PINCTRL_MSM are indented and
expressed as dependening but some not, because of other Kconfig entries
in between,
Move all main Qualcomm SoC pin controller driver entries into new
Kconfig.msm file so they will be nicely ordered in Kconfig file (by
CONFIG_ name) and properly indented as PINCTRL_MSM dependency in
menuconfig.
Functionally this is the same, but since entire file is guarded with "if
PINCTRL_MSM" drop this dependency from individual entries.
