Subject: [Intel-gfx] [PATCH 3/5] drm/i915/dp: fix EHL/JSL max source rates calculation
Date: Thu, 12 Aug 2021 11:18:04 +0530	[thread overview]
Message-ID: <20210812054806.22745-4-animesh.manna@intel.com> (raw)
In-Reply-To: <20210812054806.22745-1-animesh.manna@intel.com>

Only higher voltage sku can support HBR3 so a condition
check added in max source rate calculation for ehl/jsl.

Bspec: 32247, 20598
