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