Analyze and fix the following issue in the Linux kernel code: arm64: dts: allwinner: Fix PMIC interrupt number
Problem Details: The "r_intc" interrupt controller on the A64 uses a mapping scheme, so the first (and only) NMI interrupt #0 appears as interrupt number 32 (cf. the top comment in drivers/irqchip/irq-sun6i-r.c). Fix that number in the interrupts property to properly forward PMIC interrupts to the CPU. Signed-off-by:...
