Update the DT to match newest Data Modul i.MX8M Plus eDM SBC rev.903
board which implements significant changes. Keep some of the rev.900
and rev.902 nodes in the DT so that a DTO can be used to support old
rev.900 and rev.902 boards easily.
The changes from rev.900 to rev.902 are:
- Both ethernet PHYs replaced from AR8031 to BCM54213PE
- Both ethernet PHYs MDIO address changed
- PCIe WiFi now comes with dedicated regulator
- I2C TPM chip address
- Additional GPIO expander for LVDS panel control added
- Current EEPROM I2C address changed
- Another optional EEPROM added onto another I2C bus
The changes from rev.902 to rev.903 are:
- Additional GPIO expander for WiFi and LVDS panel control added
- Multiple GPIOs are reassigned
