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.

v2->v3:
 * Dropped items and instead used enum for single compatible values

   the RZ/{G2L,G2UL,Five,V2L} SoCs
 * Replaced maxItems->minItems for interrupts and interrupt-names
   properties of the RZ/G3L SoC.

Where are lore links to previous dicussions? b4 adds them
automatically.

I do not understand the rationale behind the changes in previous patch
and this makes no sense without previous one, but I feel it was
discussed before. Well, not my task to keep finding them if you decide
not to use standard tools to make review easier :/

Best regards,
