Bug Description

[SRU Justification: oem-osp1-bionic]

[Impact]
Bug 1849278 introduced a regression on some Comet Lake platforms that
device may have no video output on HDMI port.

[Fix]
A currently in-review patch
https://patchwork.freedesktop.org/patch/340416 should be applied to
correct PCH's identity and restore HDMI output.

[Test Case]
1. Apply the patches to oem-osp1 kernel >= 1026 or Eoan/Focal generic
kernels.
2. Boot affected platforms with HDMI cable connected to an external
monitor.
3. Check if the monitor lights up when GDM service is started.

This was verified in to victim platforms.

[Regression Risk]
Low. This should affects only systems with matching PCH hw that is
currently affected by the regression to be fixed.

==============================================

[SRU Justification: E/F/U]

[Impact]
Some Comet Lake platforms got i915 call trace dump due to the lake of
support to its PCH id:

[Fix]
Two patches to be backported to have correct support:
* commit 37c92dc303dd "drm/i915: Add new CNL PCH ID seen on a CML
  platform" from drm-tip tree.
* patch "https://patchwork.freedesktop.org/patch/340416"

[Test Case]
1. Apply the patches to oem-osp1 kernel >= 1026 or Eoan/Focal generic
kernels.
2. Boot affected platforms with HDMI cable connected to an external
monitor.
3. Check if the monitor lights up when GDM service is started.

This was verified in to victim platforms.

[Regression Risk]
Low. This should affects only systems with matching PCH hw that is
currently affected by the regression to be fixed.

========== original bug description ==========

This is a regression caused by bug 1849278, which sends external monitor (via HDMI port) to DPMS mode.

Commit 1d6870b9f9ca "UBUNTU: SAUCE: drm/i915: Add new CNL PCH ID seen on a CML platform"[1] was originated from https://bugs.freedesktop.org/show_bug.cgi?id=112051 patch https://bugs.freedesktop.org/attachment.cgi?id=145786 , which can cause this regression and was then revised by https://bugs.freedesktop.org/attachment.cgi?id=145843 and is currently in review in https://patchwork.freedesktop.org/patch/340416/?series=69345&rev=1 .
