[PATCH] drm/msm/mdp5: Remove MSM8974v1
From: Konrad Dybcio
Date: Mon Mar 02 2026 - 08:47:20 EST
From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>
To the best of my knowledge, the v1 version of this SoC had been
superseded before any device was released on the market. Everywhere
else in the kernel, there are assumptions about the SoC being revision
2 or the later MSM8974PRO.
Remove the config for that flavor of MDP. To bring the naming in line
with the rest of the kernel, remove the v2 suffix from the remaining
config.
