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).
81 8. M1 unlocks muxes on its parent.
