For GPIO that do not use interrupts, the gpio-keys-polled drivers can be used and will still benefit from having linux key codes associated with them. Like in the previous example, create a new node under the AXI interconnect, but this time name it “gpio-keys-polled”. The structure for gpio-keys-polled is almost identical to that of gpio-keys – the polled keys do not have any interrupt capabilities, so gpio-key,wakeup is not relevant; the gpio-keys-polled driver also includes a poll-interval property, in milli-seconds. Full documentation of this driver can be found here Documentation/devicetree/bindings/input/gpio-keys-polled.txt .
