Not sure this is the right form to ask this question.
I wanted to add device tree node to support ADP5588 keypad controller which uses I2C1 bus to communicate with iMX6 processor and an external interrupt pin (GPIO)
I browsed though /Documentation/devicetree/bindings/input, but could not find any documentation related to ADP5588 keypad controller. How can I figure out device tree is supported for ADP5588 or not? If yes then where can I get node structure information.
