There's a bit more to it to enable interrupts. You would probably need to set up a chained interrupt controller in the GPIO driver, and in the DTS with a interrupt-parent and interrupts properties pointing to the AXP device itself. > Otherwise, > > Acked-by: Chen-Yu Tsai <[email protected]> Applied 9 and 10, thanks!
