    Hi!
    

    

    I work on RTD measurement based on the MAX11410 part. The hardware implementation is the same as the application note described in p.91 and p.93 of the datasheet.
    

    

    We would like to interface the MAX11410 with the existing Linux Driver.
    

    For RTD measurement, we use the IDAC mode to provide excitation current to RTD.
    

    As far as I understood (from driver source in Linux Kernel v6.6.84), the IDAC mode is not yet implemented in the driver, right? Am I missing something?
    

    

    I was wondering if there is any plan to add this feature/configuration of the MAX11410 in future Linux Kernel releases?
    

    

    With many thanks in advance for your feedback.
    

    
Antonin
