Subject: [PATCH v3 11/14] irqchip/irq-bcm7120-l2: Switch to IRQCHIP_PLATFORM_DRIVER
Date: Tue, 28 Sep 2021 11:21:36 -0700 [thread overview]
Message-ID: <20210928182139.652896-12-f.fainelli@gmail.com> (raw)
In-Reply-To: <20210928182139.652896-1-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.
To avoid using of_irq_count() which is not exported towards module,
switch the driver to use the platform_device provided by the irqchip
platform driver code and resolve the number of interrupts using
platform_irq_count().
