9fd2170d70 irqchip/renesas-rzg2l: Replace raw_spin_{lock,unlock} with guard() in rzg2l_irq_set_type()
Simplify the locking logic in rzg2l_irq_set_type() by using guard(),
eliminating the need for an explicit unlock call.

[ tglx: Remove the pointless cleanup.h include. The spinlock guards come
  	from spinlock.h ]

42972b5464 irqchip/gic-v3: Print a warning for out-of-range interrupt numbers
gic_irq_domain_translate() does not check if an interrupt number lies
within the valid range of the specified interrupt type.  Add these checks,
and print a warning if the interrupt number is out of range.

This can help flagging incorrectly described Extended SPI and PPI
interrupts in DT.

e0fcae27ff irqchip/renesas-rzg2l: Add shared interrupt support
The RZ/G3L SoC has 16 external interrupts, of which 8 are shared with TINT
(GPIO interrupts), whereas RZ/G2L has only 8 external interrupts with no
sharing. The shared interrupt line selection between external interrupt and
GPIO interrupt is based on the INTTSEL register. Add shared_irq_cnt
variable to struct rzg2l_hw_info handle these differences.

Add used_irqs bitmap to struct rzg2l_irqc_priv to track allocation state.
In the alloc callback, use test_and_set_bit() to enforce mutual exclusion
and configure the INTTSEL register to route to either the external
interrupt or TINT. In the free callback, use test_and_clear_bit() to
release the shared interrupt line and reset the INTTSEL. Also add INTTSEL
register save/restore support to the suspend/resume path.

98b24d39c8 irqchip/renesas-rzg2l: Add RZ/G3L support
The IRQC block on the RZ/G3L SoC is almost identical to the one found on
the RZ/G2L SoC, with the following differences:

 - The number of GPIO interrupts for TINT selection is 113 instead of 123.
 - The pin index and TINT selection index are not in the 1:1 map.
 - The number of external interrupts are 16 instead of 8, out of these
   8 external interrupts are shared with TINT.

Add support for the RZ/G3L driver by filling the rzg2l_hw_info table and
adding LUT for mapping between pin index and TINT selection index.

bcb3066908 irqchip/renesas-rzg2l: Split rzfive_irqc_{mask,unmask} into separate IRQ and TINT handlers
rzfive_irqc_mask() and rzfive_irqc_unmask() use hw_irq range checks to

rzfive_irqc_irq_unmask(), and rzfive_irqc_tint_unmask() — each operating
unconditionally on its respective interrupt type, removing the runtime
conditionals.

Assign the IRQ-specific handlers to rzfive_irqc_irq_chip and the
TINT-specific handlers to rzfive_irqc_tint_chip, consistent with the
separation applied to the EOI, set_type, and enable/disable callbacks in
previous patches.

0109d24b4c irqchip/renesas-rzg2l: Drop redundant IRQC_TINT_START check in rzg2l_irqc_alloc()
The check `hwirq < IRQC_TINT_START` in rzg2l_irqc_alloc() is unnecessary as
the condition is already guaranteed to be false at that point in the code.

The outer `if (hwirq > IRQC_IRQ_COUNT)` block ensures that hwirq is always
above IRQC_IRQ_COUNT before reaching this check, and since IRQC_TINT_START
<= IRQC_IRQ_COUNT, the guard can never trigger.

Remove the dead code to simplify the allocation path.

dc30127cd0 LoongArch: Override arch_dynirq_lower_bound to reserve LPC IRQs
Loongson 7A PCH chips all contain a LPC controller, which is used in
some devices to connect legacy ISA devices (e.g. 8259 PS/2 controller).

The LPC irqchip driver will register LPC interrupts at the fixed range
0~15, and the PCH PIC irqchip driver uses dynamic allocation. However the
LPC interrupt numbers are currently not exempted from dynamic allocation.

The current setup work by accident because the LPC interrupt controller is
the first consumer of PIC interrupt controller, and the PIC interrupt
number is allocated after LPC interrupts are registered. Such setup is
fragile and will stop to work when the LPC irqchip driver is reworked.

Override arch_dynirq_lower_bound() to reserve LPC interrupts from dynamic
allocation, to prevent interrupt number collision and allow rework of the
LPC irqchip driver.

1f0cf05155 irqchip/apple-aic: Add support for "apple,t8122-aic3"
Introduce support for the new AICv3 hardware block in t8122 and t603x
SoCs. AICv3 is similar to AICv2 but has an increased IRQ config offset.

These MMIO offsets are coded as properties of the "aic,3" node in Apple's
device tree. The actual offsets are the same for all SoCs starting from M3
through at least M5.

So do not bother to follow suit but use AICv3 specific defines in the
driver.  The compatible string is SoC specific so future SoCs with AICv3
and different offsets would just use their own compatible string as base
and add their new offsets.

AIC version 3 as found on the Apple M3 (t8122) is very similar to AICv2 in
its base functionality. It can use the same device tree bindings as AICv2
so add it to the AICv2 bindings. This interrupt controller is used on all
Apple SoCs starting with M3 up to at least M5.

The only apparent difference is the increased IRQ config offset. Apple's
device tree codes this new offset as property of the "aic" node but the
value stayed constant for all SoCs with "aic,3". Since the SoC specific
compatible "apple,t8122-aic3" will be only used in the driver this offset
can remain a driver implementation detail.

5e72917802 irqchip/imx-irqsteer: Add NXP S32N79 support
Add support for the interrupt steering controller found in NXP S32N79
series automotive SoCs.

The S32N79 IRQ_STEER variant differs from the i.MX version by not
implementing the CHANCTRL register. To handle this hardware difference,
introduce a device type data structure with quirks field. The
IRQSTEER_QUIRK_NO_CHANCTRL quirk skips CHANCTRL register access for S32N79
variants.

The interrupt routing functionality and register layout are otherwise
identical between the two variants.

7585a27644 irqchip/renesas-rzv2h: Handle ICU error IRQ and add SWPE trigger
Handle the RZ/V2H ICU error interrupt to help diagnose latched bus,
ECC RAM, and CA55/IP error conditions.

Support error injection via ICU_SWPE to allow testing the pseudo error
error interrupts.

Account for SoC differences in ECC RAM error register coverage so the
handler only iterates over valid ECC status/clear banks, and route the
RZ/V2N compatible to a probe path with the correct ECC range while
keeping the existing RZ/V2H and RZ/G3E handling.

61adc4813d irqchip/renesas-rzv2h: Add CA55 software interrupt support
The RZ/V2H ICU exposes four software-triggerable interrupts targeting
the CA55 cores (int-ca55-0 to int-ca55-3). Add support for these
interrupts to enable IRQ injection via the generic IRQ injection
framework.

Add a dedicated rzv2h_icu_swint_chip irq_chip for the CA55 region and
implement rzv2h_icu_irq_set_irqchip_state() to handle software interrupt
injection.

f3ebae6dc0 irqchip/renesas-rzv2h: Replace single irq_chip with per-region irq_chip instances
Replace the single rzv2h_icu_chip and its dispatcher callbacks with
dedicated irq_chip instances for each interrupt region: NMI, IRQ, and
TINT.

Move the irqd_is_level_type() check ahead of the scoped_guard in
rzv2h_icu_tint_eoi() and rzv2h_icu_irq_eoi() to avoid acquiring the
spinlock unnecessarily for level-type interrupts.

Drop the ICU_TINT_START guard from rzv2h_tint_irq_endisable() since it
is now only reachable via the TINT chip path.
