Right now they don't because you don't have a status > = "disabled" in sdm845.dtsi, but maybe you should?

But merging this as is will cause the modem to crash repeatedly until rmtfs is present. Sibi is making progress on tying this to rmtfs, which would be accompanied by the following commit: https://lore.kernel.org/lkml/20180524192141.20323-1-ramon.fried@xxxxxxxxx/ I'm okay with merging that now, to unblock the merge of this patch. Would appreciate an Ack on this. Also, Sibi, the glink-edge binding doesn't define the mbox-names property, so please drop it. Regards, Bjorn
