-/* QEMU Synchronous Serial Interface support. */

-/* In principle SSI is a point-point interface. As such the qemu
- implementation has a single slave device on a "bus".
- However it is fairly common for boards to have multiple slaves
- connected to a single master, and select devices with an external
- chip select. This is implemented in qemu by having an explicit mux device.
- It is assumed that master and slave are both using the same transfer width.
