From 6c95320d01dcac321e9e89903a26a840838a0ef6 Mon Sep 17 00:00:00 2001 From: George Shen Date: Tue, 18 Aug 2020 18:42:55 -0400 Subject: [PATCH] drm/amd/display: Rename set_mst_bandwidth to align with DP spec [Why] The function set_mst_bandwidth is poorly name since it isn't clear what it does, and it also does not reflect any part of the allocation sequence described in the DP spec. [How] Rename the function set_mst_bandwidth to set_throttled_vcp_size.
