On seeedstudio.com and everywhere else I look I only see this written
as "Sipeed M1s".

And to echo what Icenowy writes, this is better split as a .dtsi for
the Sipeed M1s module that can then be included by a .dts for the
using the module with the dock, which should then have something like

model = "Sipeed M1s Dock";
