111 Specifier for a GPIO connected to the panel enable control signal. The
112 enable signal is active high and enables operation of the panel. This
113 property can also be used for panels implementing an active low power down
114 signal, which is a negated version of the enable signal. Active low enable
115 signals (or active high power down signals) can be supported by inverting
