From: Emanuele Ghidoli <emanuele.ghidoli@xxxxxxxxxxx> The Toradex Embedded Controller serves as a system controller, providing system power-off and restart functionalities The two variants, Smarc iMX95 and Smarc iMX8P, have a compatible I2C interface. Besides this, different compatible values are defined to allow for future implementation differences.
