+From OS view the device is basically an i2c-mux used to communicate with up to

+    sbsm,i2c-retry-count = <3>;
+    #address-cells = <1>;
+    #size-cells = <0>;
+
+    channel1@1 {

channel@1

Do we have a standard node name for mux nodes? If not, we should.

No name is enforced by the i2c mux support code, but I think "i2c"
dominates, and quite possibly it is the only documented name?

The kernel generally doesn't care what node names are, but standard
naming is convention. If "i2c" is most common, then go with that.
