From: Biju Das <biju.das.jz@bp.renesas.com>
Document RZ/G3L (R9A08G046) IRQC bindings. The IRQC block on RZ/G3L SoC
is almost identical to one found on the RZ/G3S SoC with the difference
like it support more External IRQs, GPT Error Interrupts and also has
additional registers for GPT/MTU IRQ selection, shared IRQ selection
between external IRQ and TINT. Hence new generic compatible string
"renesas,r9a08g046-irqc" is added for RZ/G3L SoC.
