[PATCH 02/14] drm/mgag200: Move DAC-register setup into model-specific code
Thomas Zimmermann
tzimmermann at suse.de
Fri Jul 8 09:39:17 UTC 2022
Provide an init function for each model's DAC registers. Remove
the shared helper.
The code for initializing the DAC registers consisted of a large
table of default value, plus many exceptions for the various G200
models. Providing a per-model implementation makes if more readable.
At some point, some of the initialization should probably move into
the modesetting code.
