+Subject: [PATCH 698/773] overlays: i2c-gpio: Fix the "bus" parameter
+
+The "bus" parameter has two functions - providing unique names for
+multiple instances of the overlay, and allowing the number of the bus
+(i.e. "i2c-<bus>") to be specified. The second function hasn't worked
+as intended because the overlay doesn't include a "reg" property and
+the firmware intentionally won't create a "reg" property if one doesn't
+already exist.
+
+Allow the bus numbering scheme to work as intended by providing a "reg"
+with a default value that means "the next available one".
+
