This compatible string is still not documented (AFAIK). 2. As I understand it, TI is a second source for this NXP-designed chip, i.e. it manufactures chips with identical logic (not clones) under license. They should not be distinguishable in software. 3. For the same reason, there is no guarantee that the board manufacturer won't populate boards with PCF8575 chips from the other source in future.
