+ * Descriptor: HWC2_FUNCTION_GET_DISPLAY_IDENTIFICATION_DATA
+ * Optional for HWC2 devices
+ *
+ * If supported, getDisplayIdentificationData returns the port and data that
+ * describe a physical display. The port is a unique number that identifies a
+ * physical connector (e.g. eDP, HDMI) for display output. The data blob is
+ * parsed to determine its format, typically EDID 1.3 as specified in VESA
+ * E-EDID Standard Release A Revision 1.
+ *
+ * Devices for which display identification is unsupported must return null when
+ * getFunction is called with HWC2_FUNCTION_GET_DISPLAY_IDENTIFICATION_DATA.
+ *
+ * Parameters:
+ *   outPort - the connector to which the display is connected;
+ *             pointer will be non-NULL
+ *   outDataSize - if outData is NULL, the size in bytes of the data which would
+ *       have been returned; if outData is not NULL, the size of outData, which
+ *       must not exceed the value stored in outDataSize prior to the call;
+ *       pointer will be non-NULL
+ *   outData - the EDID 1.3 blob identifying the display
+ *
+ * Returns HWC2_ERROR_NONE or one of the following errors:
