+Subject: [PATCH] overlays: gpio-shutdown: Add debounce parameter
+
+Give the gpio-shutdown overlay a debounce parameter that requires
+the GPIO to be held at the relevant level for a specified number
+of milliseconds. The default value is 100 - higher than the driver
+default of 5ms to avoid unfortunate glitches.
+
