[PATCH RFC v3 09/12] drm/msm: generate headers on the fly

Dmitry Baryshkov dmitry.baryshkov at linaro.org
Fri Mar 15 11:46:31 UTC 2024 

Generate DRM/MSM headers on the fly during kernel build. This removes a
need to push register changes to Mesa with the following manual
synchronization step. Existing headers will be removed in the following
commits (split away to ease reviews).
