[PATCH v4 10/10] arm64: dts: allwinner: Move wakeup-capable IRQs to r_intc

All IRQs that can be used to wake up the system must be routed through r_intc, so they are visible to firmware while the system is suspended. 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.

[PATCH v4 05/10] ARM: dts: sunxi: Rename nmi_intc to r_intc

The R_INTC block controls more than just the NMI, and it is a different hardware block than the NMI INTC found in some other Allwinner SoCs, so the label "nmi_intc" is inaccurate. Name it "r_intc" to match the compatible and to match the few references in the vendor documentation. Signed-off-by:

[PATCH v4 00/10] sunxi: Support IRQ wakeup from deep sleep

Allwinner sun6i/sun8i/sun50i SoCs (A31 and newer) have two interrupt controllers: GIC and R_INTC. GIC does not support wakeup. R_INTC handles the external NMI pin, and provides 32+ IRQs to the ARISC. The first 16 of these correspond 1:1 to a block of GIC IRQs starting with the NMI. The last 13-16

[PATCH v4 01/10] dt-bindings: irq: sun6i-r: Split the binding from sun7i-nmi

The R_INTC in the A31 and newer sun8i/sun50i SoCs has additional functionality compared to the sun7i/sun9i NMI controller. Among other things, it multiplexes access to up to 128 interrupts corresponding to (and in parallel to) the first 128 GIC SPIs. This means the NMI is no longer the

[PATCH v4 02/10] dt-bindings: irq: sun6i-r: Add a compatible for the H3

The Allwinner H3 SoC contains an R_INTC that is, as far as we know, compatible with the R_INTC present in other sun8i SoCs starting with the A31. Since the R_INTC hardware is undocumented, introduce a new compatible for the R_INTC variant in this SoC, in case there turns out to be some difference.

[PATCH v4 03/10] irqchip/sun6i-r: Use a stacked irqchip driver

The R_INTC in the A31 and newer sun8i/sun50i SoCs is more similar to the original sun4i interrupt controller than the sun7i/sun9i NMI controller. 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
