AM4378: PMIC Linux Integration

Part Number: AM4378
Other Parts Discussed in Thread: TPS65218

HI All,

Due to current market constraints, our hardware team is actively trying to replace the PMIC (TPS65218) with a discrete solution on a custom board we have (very similar to GP EVM for AM437x). 

It then dawned on our software team that there may exist some tight integration with that chip and the embedded linux image.

What are the implications to the embedded linux image if the PMIC was no longer responding on the I2C bus?

Do we need to remove it from the device tree?

Are the changes we may need in u-boot?

Thanks in advance for any responses.

Nathan
