I want I want to use external interrupts for P2020 in Linux. What should I do?How do I configure DTS?
Or which documents should I look at and where to get them
Are you creating a totally new driver for an interrupt enabled device, or trying to re-use an existing driver for an externally connected peripheral on P2020?
