--- Comment #17 from Lu, Han <han.lu at intel.com> ---
The issue is fixed with APL stepping B0, but we need to wait for the patches be
upstreamed.

Issues being fixed:
1. Bug 92916 - [BXT-P APL] Can't light on HDMI monitor if boot up without
monitor connected
2. Bug 92805 - [BXT-P APL] [Audio] Cannot refresh ELD information on the text
mode and the UI mode

Reworks required:
1. Reverse O-03 on APL RVP1A, for APL B0 stepping Soc upgrade.
2. Apply R19 on APL RVP1A, for APL B0 stepping Soc upgrade.
3. Apply F-28C on APL RVP1A, for HDMI to use DDI-1 instead of DDI-0
(Optional 4. Apply F-27 on APL RVP1A, for DP to use DDI-0 instead of DDI-1)

Our environment to check the issue: (the patches are not applicable to latest
commits since code changed, we used an commit of around March 10 instead)
