Agreed on all the stuff above.

We always used underscores, this goes back to the first Colibri specific
device tree: tegra20-iris-512.dts.
I would rather prefer to not change this for the sake of consistency...
What do you think?

Yeah my idea behind this is that "imx7d" is still kind of the base name
of that SoC. But I agree for the bindings it does not make that much
sense.
I have to add imx7s to arch/arm/mach-imx/mach-imx7d.c though.
