We already have mechanisms in the core for drivers to tell the core how long a ramp they need for a given voltage transition - you should extend them (probably needs a set_voltage_time() operation adding) so that anything like this can be done in the core rather than open coded in drivers. -------------- next part -------------- A non-text attachment was scrubbed...
