+title: Parade pt touch controller
+
+description: The Parade Touch controller is connected to the
+  host processor via I2C. The controller generates interrupts
+  when the user touches the panel. The host controller is
+  expected to read the touch coordinates over I2C and pass
+  the coordinates to the rest of the system.
