65 one or more downstream I2C buses, and it can be commanded to connect
66 any one of the downstream buses to the upstream bus.
67 Some hardware may be able to connect multiple downstream buses at the
75 the active downstream bus.
80 Some mux hardware has the ability to disconnect all downstream buses
82 Other hardware must always have one of the downstream buses connected.
84 downstream bus (if any) should be connected while in the idle state.
85 In the absence of such configuration, whichever downstream bus was
88 When an I2C slave device on a bus downstream of a mux initiates I/O,
96 connects the upstream I2C bus to the downstream bus which hosts the
98 The mux hardware maintains that upstream-to-downstream connection until
138 instance for every downstream bus supported by the chip.
139 There is currently no way to indicate used versus unused downstream buses.
