This commit has been validated on APL NUC and Gordon Peak with 3 connected displays. This PR transfers the commit to Github since Android Q will be released shortly (presumably tomorrow).

Add HWC2.3 GetDisplayIdentificationData

This API retrieves the EDID metadata for all display devices connected to a video source. The metadata identifies the port, and describes the display type, such as HDMI or DisplayPort and their capabilities. The data blob returned by the API contains the supported EDID format, typically EDID 1.3, as specified in VESA E-EDID Standard Release A Revision 1. Note that EDID 1.4 metadata format is not supported since the format is incompatible with the HDMI specification.

Tests: Validated on Gordon Peak with three connected displays Tracked-On: https://jira.devtools.intel.com/browse/OAM-71878 Signed-off-by: Michele Lim michele.lim@intel.com
