H A Di2c-topology.rst2 I2C muxes and complex topologies
19 Several types of hardware components such as I2C muxes, I2C gates and I2C
39 There are two variants of locking available to I2C muxes, they can be
40 mux-locked or parent-locked muxes.
43 Mux-locked muxes
46 Mux-locked muxes does not lock the entire parent adapter during the
47 full select-transfer-deselect transaction, only the muxes on the parent
48 adapter are locked. Mux-locked muxes are mostly interesting if the
72 2. M1 locks muxes on its parent (the root adapter in this case).
