Document RZ/G3L (R9A08G046) IRQC. The IRQC block on the RZ/G3L SoC is nearly identical to that found on the RZ/G3S SoC, with the following differences: it supports more external interrupts and GPT error interrupts, and adds registers for GPT/MTU interrupt selection and shared interrupt selection between external interrupt and TINT. A new compatible string "renesas,r9a08g046-irqc" is therefore introduced for the RZ/G3L SoC.

IA55 performs various interrupt controls including synchronization for the external
|
|
interrupts of NMI, IRQ, and GPIOINT and the interrupts of the built-in peripheral
|
|
interrupts output by each IP. And it notifies the interrupt to the GIC
|
|
- IRQ sense select for 8 external interrupts, mapped to 8 GIC SPI interrupts
|
|
- GPIO pins used as external interrupt input pins, mapped to 32 GIC SPI interrupts
|
|
- NMI edge select (NMI is not treated as NMI exception and supports fall edge and
|
|
stand-up edge detection interrupts)
