From 155668ef412fc82ff3172666831d95770141cdd6 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Thu, 27 Jul 2023 14:20:10 -0700 Subject: [PATCH] drm/msm/adreno: Use quirk to identify cached-coherent support It is better to explicitly list it. With the move to opaque chip-id's for future devices, we should avoid trying to infer things like generation from the numerical value.
