Patrick; I was looking at a patch series of yours that landed, https://github.com/qemu/qemu/blob/master/hw/arm/aspeed.c#L517 <-- in this line you're referencing a device that appears to be missing from qemu - namely, the pca i2c mux. My question is to the community at large, and you also, is anyone currently implementing this i2c-mux or a similar one? Thanks, Patrick
