From mboxrd@z Thu Jan 1 00:00:00 1970 From: hdegoede@redhat.com (Hans de Goede) Date: Mon, 26 May 2014 09:47:56 +0200 Subject: [PATCH 01/11] pinctrl: sunxi: create irq/pin mapping during init In-Reply-To: <1401090486-4414-1-git-send-email-hdegoede@redhat.com> References: <1401090486-4414-1-git-send-email-hdegoede@redhat.com> Message-ID: <1401090486-4414-2-git-send-email-hdegoede@redhat.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Chen-Yu Tsai The irq/pin mapping is used to lookup the pin to mux to the irq function when the irq is enabled. It is created when gpio_to_irq is called. Creating the mapping during init allows us to map the interrupts directly from the device tree.
