[PATCH v3 13/14] drm/mgag200: Move CRTC atomic_enable to model-specific code
Thomas Zimmermann
tzimmermann at suse.de
Thu Jul 28 12:41:02 UTC 2022
The CRTC atomic_enable helper contains per-model branches for
G200ER, G200EV and G200SE devices. Implement a dedicated helper
for each of them and remove the branches from the shared helper.
