Subject: [PATCH v4 5/6] gpio: max77620: Use irqchip template
Date: Thu, 9 Jul 2020 20:12:02 +0300 [thread overview]
Message-ID: <20200709171203.12950-6-digetx@gmail.com> (raw)
In-Reply-To: <20200709171203.12950-1-digetx@gmail.com>
This change addresses one of the GPIO-core TODOs for the MAX77620 driver
which requires modern drivers to use the irqchip template. Instead of
using the GPIO's irqchip-helpers for creating the IRQ domain, the
gpio_irq_chip structure is now filled by the driver itself and then
gpiochip_add_data() takes care of instantiating the IRQ domain for us.
