+Description:
+		d3cold_allowed is bit to control whether the corresponding PCI
+		device can be put into D3Cold state.  If it is cleared, the
+		device will never be put into D3Cold state.  If it is set, the
+		device may be put into D3Cold state if other requirements are
+		satisfied too.  Reading this attribute will show the current
+		value of d3cold_allowed bit.  Writing this attribute will set
+		the value of d3cold_allowed bit.
