From: Chen-Yu Tsai <redacted> 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.
Can you be a bit more precise on this? What is the issue that this patch fix? Maxime -- Maxime Ripard, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com
