Subject: Re: [PATCH 06/20] drm/i915/mtl: Add vswing programming for C10 phys
to fix the FIXME in intel_cx0_phy_set_signal_levels() we need the following patch snipet to be incorporated into this patch.

Thanks Clint! I will add this snippet into v2 version of the C10/C20/TBT patch series.

Subject: [PATCH 06/20] drm/i915/mtl: Add vswing programming for C10 phys
From: Radhakrishna Sripada <radhakrishna.sripada at intel.com<mailto:radhakrishna.sripada at intel.com>>
C10 phys uses direct mapping internally for voltage and pre-emphasis levels.
Program the levels directly to the fields in the VDR Registers.
