Among other things, it multiplexes up to 128 interrupts corresponding to (and in parallel to) the first 128 GIC SPIs. This means the NMI is no longer the lowest-numbered interrupt, since it is SPI 32 or 96 (depending on SoC). To allow access to all multiplexed IRQs, the R_INTC requires a new binding where the interrupt number matches the GIC interrupt number. For simplicity, copy the three-cell GIC binding; this disambiguates interrupt 0 in the old binding (the NMI) from interrupt 0 in the new binding (SPI 0) by the number of cells.

It is used for two distinct purposes: - To control the trigger, latch, and mask for the NMI input pin - To provide the interrupt input for the ARISC coprocessor As this interrupt controller is not documented, information about it comes from vendor-provided firmware blobs and from experimentation. Like the original sun4i interrupt controller, it has: - A VECTOR_REG at 0x00 (configurable via the BASE_ADDR_REG at 0x04) - A NMI_CTRL_REG, PENDING_REG, and ENABLE_REG as used by both the sun4i and sunxi-nmi drivers - A MASK_REG at 0x50 - A RESP_REG at 0x60 Differences from the sun4i interrupt controller appear to be: - It only has one or two registers of each kind (max 32 or 64 IRQs) - Multiplexing logic is added to support additional inputs - There is no FIQ-related logic - There is no interrupt priority logic In order to fulfill its two purposes, this hardware block combines four types of IRQs. First, the NMI pin is routed to the "IRQ 0" input on this chip, with a trigger type controlled by the NMI_CTRL_REG. The "IRQ 0 pending" output from this chip, if enabled, is then routed to a SPI IRQ input on the GIC. In other words, bit 0 of IRQ_ENABLE_REG *does* affect the NMI IRQ seen at the GIC. The NMI is followed by a contiguous block of 15 "direct" (my name for them) IRQ inputs that are connected in parallel to both R_INTC and the GIC. Or in other words, these bits of IRQ_ENABLE_REG *do not* affect the IRQs seen at the GIC. Following the direct IRQs are the ARISC's copy of banked IRQs for shared peripherals. These are not relevant to Linux. The remaining IRQs are connected to a multiplexer and provide access to the first (up to) 128 SPIs from the ARISC. This range of SPIs overlaps with the direct IRQs. Finally, the global "IRQ pending" output from R_INTC, after being masked by MASK_REG and RESP_REG, is connected to the "external interrupt" input of the ARISC CPU. This path is also irrelevant to Linux. Because of the 1:1 correspondence between R_INTC and GIC inputs, this is a perfect scenario for using a stacked irqchip driver. We want to hook into enabling/disabling IRQs to add more features to the GIC (specifically to allow masking the NMI and setting its trigger type), but we don't need to actually handle the IRQ in this driver. And since R_INTC is in the always-on power domain, and its output is connected directly in to the power management coprocessor, a stacked irqchip driver provides a simple way to add wakeup support to this set of IRQs. That is the next patch; for now, just the NMI is moved over. To allow access to all multiplexed IRQs, this driver requires a new binding where the interrupt number matches the GIC interrupt number. (This moves the NMI number from 0 to 32 or 96, depending on the SoC.) For simplicity, copy the three-cell GIC binding; this disambiguates interrupt 0 in the old binding (the NMI) from interrupt 0 in the new binding (SPI 0) by the number of cells. This commit mostly reverts commit 173bda53b340 ("irqchip/sunxi-nmi: Support sun6i-a31-r-intc compatible").

Then restore the original set of enabled IRQs (only the NMI) during resume. This serves two purposes. First, it lets power management firmware running on the ARISC coprocessor know which wakeup sources Linux wants to have enabled. That way, it can avoid turning them off when it shuts down the remainder of the clock tree. Second, it preconfigures the coprocessor's interrupt controller, so the firmware's wakeup logic is as simple as waiting for an interrupt to arrive. The suspend/resume logic is not conditional on PM_SLEEP because it is identical to the init/shutdown logic. Wake IRQs may be enabled during shutdown to allow powering the board back on. As an example, see commit a5c5e50cce9d ("Input: gpio-keys - add shutdown callback").

Name it "r_intc" to match the compatible and to match the few references in the vendor documentation.

Update the device trees to use the new binding.

Update the device trees to use the new binding.

In addition to the external NMI input, which is already routed through r_intc, these include PIO and R_PIO (gpio-keys), the LRADC, and the RTC.
