Subject: [PATCH v3 09/16] gpiolib: Introduce gpiochip_irqchip_add_domain()
Date: Thu, 23 Apr 2020 19:45:36 +0200	[thread overview]
Message-ID: <20200423174543.17161-10-michael@walle.cc> (raw)
In-Reply-To: <20200423174543.17161-1-michael@walle.cc>

This connects an IRQ domain to a gpiochip and reuses gpiochip_to_irq().
