From c4cb38b54b365edafb351e5371b9ae9eebf8e805 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 3 Dec 2021 14:35:06 +0100 Subject: dt-bindings: input: gpio-keys: Fix interrupts in example The "interrupts" property in the example looks weird: - The type is not in the last cell, - Level interrupts don't work well with gpio-keys, as they keep the interrupt asserted as long as the key is pressed, causing an interrupt storm. Use a more realistic falling-edge interrupt instead.
