We can use of_driver_match_device() to make this simpler.

I want to use the returned "match".
The of_driver_match_device() just checks if it matches or not,
so I do not think it can be the replacement.

I can use of_match_device() instead, if you like.

Sorry I meant of_device_get_match_data().

devm_get_regmap(dev->parent) should work then? Why do we need to
use OF APIs?

"git grep devm_get_regmap" did not hit anything.

Where is it defined?

Sorry I meant dev_get_regmap().
