From a8064d577dab1a81222a50c2de66a2de495f14f4 Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Mon, 16 Sep 2019 16:32:51 -0700 Subject: [PATCH] drm/i915/cml: Add second PCH ID for CMP The CMP PCH ID we have in the driver is correct for the CML-U machines we have in our CI system, but the CML-S and CML-H CI machines appear to use a different PCH ID, leading our driver to detect no PCH for them.
