   ### Is your feature request related to a problem? Please describe.
   
   According to CONFIG_SERIAL_TIOCSERGSTRUCT documentation:
   
                   As a debug option, many serial bottom half drivers support 
the TIOCSERGSTRUCT
                   that allows you to get the internal driver data structure.  
By default, this
                   IOCTL is not supported in order to reduce footprint.  But if 
(1) the driver
                   supports the TIOCSERGSTRUCT ioctl, and (2) this option is 
selected, then
                   support for the TIOCSERGSTRUCT will be enabled.
   
   Except for that basic explanation, there is no Documentation/ about it and 
how to use it
   
   ### Describe the solution you'd like
   
   We need to add Documentation/ explaining how it can be used
   
   ### Describe alternatives you've considered
   
   N/A
   
   ### Verification
   
   - [x] I have verified before submitting the report.
