All those sound like SoC components. In that case it sounds fine to have
the device compatible contain the SoC name. We're talking here about
external, detachable devices.

No, Sebastien's example was just a hypothetical case. Here, using your
way of having SoC specific data in the .dts, we would have
"sharp,ls037v7dw01-omap-dss", and in Sebastien's example with a touch
sensor we'd have, say, "synaptics,xyz123-omap-spi".
