Subject: [PATCH 3/9] irqchip/jcore-aic: Kill use of irq_create_strict_mappings()
Date: Tue, 6 Apr 2021 10:35:51 +0100 [thread overview]
Message-ID: <20210406093557.1073423-4-maz@kernel.org> (raw)
In-Reply-To: <20210406093557.1073423-1-maz@kernel.org>
irq_create_strict_mappings() is a poor way to allow the use of
a linear IRQ domain as a legacy one. Let's be upfront about it.
