Without schematics, it's hard to say if this is needed for SK-RZG1M, too. The Board Hardware Manual states SK-RZG1M has both DA9063 and DA9210. It does state DA9063 is connected to IRQ2, but doesn't mention an interrupt line for DA9210, so we don't know if they share IRQ2. Note that the Koelsch fails to mention that DA9210 uses IRQ2, so this doesn't mean much. For Porter we do not have the quirk enabled, while it has both regulators, too. You can try to enable regulator-quirk-rcar-gen2.c for "renesas,sk-rzg1m" too, and see what's printed by the kernel after a cold boot...
