23 I2C transfers, and all adapters with a parent are part of an "i2c-mux"
26 Depending of the particular mux driver, something happens when there is
27 an I2C transfer on one of its child adapters. The mux driver can
28 obviously operate a mux, but it can also do arbitration with an external
29 bus master or open a gate. The mux driver has two operations for this,
38 mux-locked or parent-locked muxes. As is evident from below, it can be
39 useful to know if a mux is mux-locked or if it is parent-locked. The
