No. Otherwise it'll become too convoluted for proper debugging and
overall expectation.
The BAUM driver supports TSI emulation as a convenience only. It
certainly is not the best mode of operation for any BAUM user. So any
autoprobe over the serial port should stick to native protocol for each
driver. Overriding that is easy enough if someone insists to use a BAUM
display with TSI emulation over the serial port, so it is not a good
idea to try to have smart rules like "if the TSI driver is not there
then let's let the BAUM driver autodetect it" which might obfuscate a
real error like a missing TSI driver for legitimate usage.
Over USB this is a non issue as the BAUM driver will only accept to use
the TSI mode with real BAUM (or equivalent) hardware which is perfectly
sensible.
