Subject: [PATCH 1/2] irqchip: irq-meson-gpio: make it possible to build as a module
Date: Thu,  2 Sep 2021 15:49:13 +0200	[thread overview]
Message-ID: <20210902134914.176986-2-narmstrong@baylibre.com> (raw)
In-Reply-To: <20210902134914.176986-1-narmstrong@baylibre.com>

In order to reduce the kernel Image size on multi-platform distributions,
make it possible to build the Amlogic GPIO IRQ controller as a module
by switching it to a platform driver.

Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>
