+What:           /sys/devices/.../coredump
+Date:           December 2017
+Contact:        Arend van Spriel <aspriel@gmail.com>
+Description:
+                The /sys/devices/.../coredump attribute is only present when the
+                device is bound to a driver, which provides the .coredump()
+                callback. The attribute is write only. Anything written to this
+                file will trigger the .coredump() callback.
+
+                Available when CONFIG_DEV_COREDUMP is enabled.
