Subject: [RFC] iio: magnetometer: mlx90393 - regmap vs command-based access
Date: Thu, 23 Apr 2026 17:48:34 +0530	[thread overview]
Message-ID: <20260423121834.4244-1-nikhilgtr@gmail.com> (raw)

Hi,

I am working on adding support for the MLX90393 magnetometer.

The device uses a command-based protocol (e.g. SM, RM, RR)
rather than a traditional register map.

Before proceeding, I wanted to clarify the preferred design:

- Should regmap be used in such cases, even without a linear
  register map?

- Or is it acceptable to implement a custom command-based
  abstraction layer?

My understanding is that regmap may not be a good fit here,
but I would appreciate guidance before implementing.

Also, pointers to similar IIO drivers would be helpful.

Thanks,
Nikhil Gautam
