[PATCH v4 18/19] irqchip/mvebu-odmi: Use irq_domain_create_hierarchy()

From: Johan Hovold <johan+linaro@kernel.org>
Date: 2023-01-16 13:51:32
Also in: linux-mips, lkml, platform-driver-x86
Subsystem: arm/marvell kirkwood and armada 370, 375, 38x, 39x, xp, 3700, 7k/8k, cn9130 soc support, irqchip drivers, the rest · Maintainers: Andrew Lunn, Gregory Clement, Sebastian Hesselbarth, Thomas Gleixner, Linus Torvalds

Use the irq_domain_create_hierarchy() helper to create the hierarchical
domain, which both serves as documentation and avoids poking at
irqdomain internals.
