Explicitely initializing all registers sounds reasonable. Should work

And it is not so hard to do. There are 30 writable registers on the 16
LED variant. But a lot of them are identical, one per LED.
I looked at regmap, and I am confused by its regmap_defaults and the notion
of a cache. I would like to just add some default values and let the regmap
infrastructure copy them into the device for me.
- Is this supported by the regmap core?
- Do I need to enable some regmap cache for this? (Probably a flat one.)
- Are there some side effects of the regmap cache?
I'm asking because the documentation in the .h files does not answer these
questions for me.
With kind regards,
Jan
