Core changes:
- Perform basic checks on pin config properties so as not to
allow directly contradictory settings such as setting a pin
to more than one bias or drive mode.
- Handle input-threshold-voltage-microvolt property.
- Introduce pinctrl_gpio_get_config() handling in the core for
SCMI GPIO using pin control.
New drivers:
- GPIO-by-pin control driver (also apperaing in the GPIO pull
request) fulfilling a promise on a comment from
Grant Likely many years ago: "can't GPIO just be a front-end
for pin control?" it turns out it can, if and only if you
design something new from scratch, such as SCMI.
- Broadcom BCM7038 as a pinctrl-single delegate.
- Mobileye EyeQ6Lplus OLB pin controller.
- Qualcomm Eliza and Hawi families TLMM pin controllers.
- Qualcomm SDM670 and Milos family LPASS LPI pin controllers.
- Qualcomm IPQ5210 pin controller.
- Realtek RTD1625 pin controller support.
- Rockchip RV1103B pin controller support.
- Texas Instruments AM62L as a pinctrl-single delegate.
Improvements:
- Set config implementation for the Spacemit K1 pin controller.

Pull gpio updates from Bartosz Golaszewski:
"For this merge window we have two new drivers: support for
GPIO-signalled ACPI events on Intel platforms and a generic
GPIO-over-pinctrl driver using the ARM SCMI protocol for
controlling pins.
Several things have been reworked in GPIO core: we unduplicated GPIO
hog handling, reduced the number of SRCU locks and dereferences,
improved support for software-node-based lookup and removed more
legacy code after converting remaining users to modern alternatives.
There's also a number of driver reworks and refactoring, documentation
updates, some bug-fixes and new tests.
GPIO core:
- defer probe on software node lookups when the remote software node
exists but has not been registered as a firmware node yet
- unify GPIO hog handling by moving code duplicated in OF and ACPI

Add the match data for the pinctrl found in the EyeQ6Lplus OLB. The pin
control is identical in function to the one present in the EyeQ5 but

Instead of using the pin descriptions, pin functions and register offsets
of the EyeQ5 directly, access those via a pointer to a newly introduced
struct eq5p_match_data.
This structure contains, in addition to the pin descriptions and pin
functions, an array of pin banks. Each bank holds the number of pins
and the register offsets.
All functions accessing a pin now use a pointer to a bank structure and
an offset inside that bank. The conversion from a pin number to a bank
and an offset is done in the new function eq5p_pin_to_bank_offset(),
which replace eq5p_pin_to_bank() and eq5p_pin_to_offset().
All the data related to the EyeQ5 is declared with the eq5p_eyeq5_
prefix to distinguish it from the common code.
During the probe, we use the parent OF node to get the match data.
We cannot directly use an OF node since pinctrl-eyeq5 is an auxiliary
device of clk-eyeq.

This issue has always been present, but has been latent until commit
"f9f4fda15e72" ("pinctrl: mcp23s08: init reg_defaults from HW at probe and
switch cache type"), which correctly removed reg_defaults from the regmap
and as a side effect changed the behavior of the interrupt handler so that
the real value of the MCP_GPINTEN register is now being read from the chip
instead of using a bogus 0 default value; a non-zero value for this
register can trigger the invocation of a nested handler which may not exist
(yet).
Fix this issue by disabling all pin interrupts during initialization.

[linusw@kernel.org: Dropped intr_target_reg]
Signed-off-by: Linus Walleij <linusw@kernel.org>
On all Qualcomm TLMM generations from APQ8084 onwards, the interrupt
target routing bits are located in the same register as the interrupt
configuration bits (intr_cfg_reg). Only five older SoCs — APQ8064,
IPQ8064, MDM9615, MSM8660 and MSM8960 — have a genuinely separate
interrupt target routing register at a different offset (0x400 + 0x4 * id).
Replace MSM_ACCESSOR(intr_target) with a custom accessor that falls back
to intr_cfg_reg when intr_target_reg is zero. Apply the same fallback in
the SCM path. Drop the now-redundant .intr_target_reg initializer from
all SoC drivers where it duplicated intr_cfg_reg, keeping it only in
the five drivers where it genuinely differs.

The intr_target_bit for Eliza was incorrectly set to 5, which is the
value used by older Qualcomm SoCs (e.g. SM8250, MSM8996, X1E80100).
Newer SoCs such as SM8650, SM8750, Milos, and Kaanapali all use
bit 8 for the interrupt target field in the TLMM interrupt configuration
register.
Eliza belongs to the newer generation and should use bit 8 to correctly
route interrupts to the KPSS (Applications Processor). Using the wrong
bit position means the interrupt target routing is silently misconfigured,
which can result in GPIO interrupts not being delivered to the expected
processor.
Fix this by aligning Eliza with the correct value used by its peer SoCs.

Recent changes in the Allwinner pinctrl/GPIO IP made us add some quirks,
which the new SoCs (A523 family) need to use. We now have a comfortable
"flags" field on the per-SoC setup side, to tag those quirks we need, but
were translating those flag bits into specific fields for runtime use, in
the init routine.
Now the newest Allwinner GPIO IP adds even more quirks and exceptions,
some of a boolean nature.
To avoid inventing various new boolean flags for the runtime struct
sunxi_pinctrl, let's just directly pass on the flags variable used by the
setup code, so runtime can check for those various quirk bits directly.
Rename the "variant" member to "flags", and directly copy the value from
the setup code into there. Move the variant masking from the init
routine to the functions which actually use the "variant" value.
This mostly paves the way for the new A733 IP generation, which needs
more quirks to be checked at runtime.
