Can we please keep the table sorted?

This needs braces. Please fix globally.

Could you please add a comment what the somewhat cryptic name
"set_dcd_rst_v1" is supposed to mean? Similar for the other functions
like set_dcd_rst_v2() etc.?

It seems these functions can run into error situations - yet they are
of type void, i. e. they don't return any information about such
errors to their callers. In the end, you cannot test the result oif
running the command to find out if it had worked or not.
This must be fixed (globally).

Your nesting is too deep. Consider reorganizing the code.
Stefano, Albert - I apologize for the late review. Please don't pull
this into mainline as is.
