Subject: [PATCH 4/5] drm/msm/adreno: Move hwcg table into a6xx specific info
Date:   Tue,  5 Dec 2023 14:03:30 -0800
Message-ID: <20231205220526.417719-5-robdclark@gmail.com>

From: Rob Clark <robdclark@chromium.org>

Introduce a6xx_info where we can stash gen specific stuff without
polluting the toplevel adreno_info struct.
