+description:
+  The Chrontel CH7322 is a discrete HDMI-CEC controller. It is
+  programmable through I2C and drives a single CEC line.

+      Reference to the GPIO connected to the RESET pin, if any. This
+      pin is active-low.

+
+  standby-gpios:
+    description:
+      Reference to the GPIO connected to the OE pin, if any. When low
+      the device will respond to power status requests with "standby"
+      if in auto mode.
