+Subject: [PATCH] pinctrl: sunxi: create irq/pin mapping during init
+
+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.
