Subject: [PATCH v6 08/13] irqchip/irq-brcmstb-l2: Switch to IRQCHIP_PLATFORM_DRIVER
Date: Wed, 20 Oct 2021 11:48:54 -0700	[thread overview]
Message-ID: <20211020184859.2705451-9-f.fainelli@gmail.com> (raw)
In-Reply-To: <20211020184859.2705451-1-f.fainelli@gmail.com>

Allow the user selection and building of this interrupt controller
driver as a module since it is used on ARM/ARM64 based systems as a
second level interrupt controller hanging off the ARM GIC and is
therefore loadable during boot.
