+		help
+		  Sets the maximum amount of time in milliseconds to wait for a response from the MTCH9010

+		bool "Override Delay if not Wake on Request"
+		default y
+		help
+		  If the MTCH9010 has a sleep period defined, the wake pin will not wake the device.
+		  If this option is set, the API will allow for <sleep period + timeout> length
