Hi Krzysztof,

You are right, the commit message did not sufficiently explain the
motivation.

The device has always required firmware; previously the driver assumed
a single default firmware file name suitable for the reference design.
What changes here is that different boards may use different electrode
layouts and mechanical structures, which require distinct calibration
and configuration data.

I will update the commit message in v3 to clearly describe this and to
clarify that the property represents board-level hardware differences.

Sorry for the confusion, and thank you for the review.

Best regards,
Yasin Lee
