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. Signed-off-by: Chen-Yu Tsai <redacted> Signed-off-by: Hans de Goede <redacted>
This is exactly correct. Patch applied. I tried to hack the sunxi driver to even use the gpiolib irqchip helpers but exactly this complex map thing in ->irq_array[] git me stuck. If any of you guys could be so nice to take a stab at this (compare to other commits converting drivers to use gpiolibs irqchip helpers) then I'd be very happy. Yours, Linus Walleij
