Go ahead and document what's on the other end. Signed-off-by: Andrew Halaney --- Changes since v1: * Document i2c12 having a max20411 (Shazad) In v1 I said i2c12 was not connected, that's not true though (I just have a board schematic which shows it not connected, but it _is_ connected on the SIP/SOM, which I verified with series [0]). I debated waiting for Bjorn to sort out appropriate label names over at [0] (and follow suit in a third patch here), but decided to get this series out again to clean up the current warnings while that's worked out. Once [0] is resubmitted I'll submit a separate patch to enable the max20411 on this board as well!
