From e5490464f45db8b8006bc62d29ec9280debd0ef9 Mon Sep 17 00:00:00 2001 From: SivapiriyanKumarasamy Date: Tue, 19 Mar 2019 15:21:50 -0400 Subject: [PATCH] drm/amd/display: fix dp_hdmi_max_pixel_clk units [Why] We are incorrectly using dp_hdmi_max_pixel_clk because the units are not clear. [How] Rename to dp_hdmi_max_pixel_clk_in_khz, and change mode timing validation to use the value correctly.
