From a3431650f30a94b179d419ef87c21213655c28cd Mon Sep 17 00:00:00 2001 From: Chaitanya Kumar Borah Date: Wed, 18 Oct 2023 17:06:22 +0530 Subject: [PATCH] drm/i915/mtl: Support HBR3 rate with C10 phy and eDP in MTL eDP specification supports HBR3 link rate since v1.4a. Moreover, C10 phy can support HBR3 link rate for both DP and eDP. Therefore, do not clamp the supported rates for eDP at 6.75Gbps.
