So the bq24735 is populated under the EC's 'i2c-tunnel' property which is there to specifically interface it's child devices to the host. So I am a bit confused why this is expose to the host if it should not be used? Again you may right and I did find the original series [0] for this which specifically references the Acer Chromebook that needs this. However, I am not sure why this was never populated? Is there any other history here? What is the actual problem you see without making this change? The original series states ... "On Acer Chromebook 13 (CB5-311) this module fails to load if the charger is not inserted, and will error when it is removed."
