Let's call it real ping, because we have warning in next due to this:

Documentation/devicetree/bindings/hwmon/ti,amc6821.example.dtb: /example-1/i2c/fan@18/i2c-mux: failed to match any schema with compatible: ['tsd,mule-i2c-mux']

So someone picked up patches before the dependencies were accepted? Bad
idea.

Can anyone pick up the i2c pieces?

They need review first. We likely have an issue with resource
availabilty here. It is that simple.

And/or fix maintainers for your subsystem?

Have you looked at the entries? They look proper to me.
