It looks like the Eagle-V3M expansion board also has an ADV7511 chip on it.
That brings it into the same category as the Wheat board, and because of a fault
on the ADV7511 reset - *both* chips will have to specify alternate custom I2C
registers. (Alternatively, the expansion board could override the reg and
reg-names of this device node to handle this as an overlay style fix up).
Not an issue with this patch - or a blocker - but something to be aware of.
