From f5de90d0829d6d007587f9ea43df4fd2a8523caa Mon Sep 17 00:00:00 2001

Subject: Expose EDID fields in DeviceProductInfo

Expose product-specific information (display name, manufacture date,
manufacturer Pnp ID) about the display or the directly connected device
on the display chain. For example, if the display is transitively
connected, these fields may contain product information about the
intermediate device.

Additionally this information can be used to prime a TV  with entries
from an infrared database for controlling connected audio and TV devices.

Bug: 145299597
Fixes: 140223709
Test: atest DisplayIdentificationTest
Change-Id: Idec0d053d945e3c171e2cdd80773c9d869934020
