Multiple MCP41010 Digital Potentiometers Work From One CS Signal
If the digital pots are intended to be operated identically then you can use common communication lines and a common chip select line providing that the communication is purely from master to slave devices. Given that the MCP41010 only has clock and data inputs this isn't going to be a problem.

Of course you could always consider a dual device like the MCP42010: -



It has a common CS line and can be daisy-chained with other MCP42xxx devices thus saving on seperate SCK and SI lines for all other instances of digipots in your circuit.
