Now there are two kinds of plan compiling button interrupt, but I don't know how to write

The interrupt number 1, direct writing, find the datasheet, but I don't know where to find, for example, I want to use GPIO3 - IO13 the interrupt pin as buttons, what's his interrupt number

2, the use of DTS interrupt - parent and interrupts properties, after setting this property, how to get in the driver interrupt of the pin number, or how to make the inside of the DTS attributes associated with button interrupt
