|

* This module supports the PCA954x and PCA984x series of I2C multiplexer/switch
|
||||
* chips made by NXP Semiconductors.
|
||||
* This includes the:
|
||||
* PCA9540, PCA9542, PCA9543, PCA9544, PCA9545, PCA9546, PCA9547,
|
||||
* PCA9548, PCA9846, PCA9847, PCA9848 and PCA9849.
|
||||
*
|
||||
* These chips are all controlled via the I2C bus itself, and all have a
|
||||
* single 8-bit register. The upstream "parent" bus fans out to two,
|
||||
* four, or eight downstream busses or channels; which of these
|
||||
* are selected is determined by the chip type and register contents. A
|
||||
* mux can select only one sub-bus at a time; a switch can select any
|
||||
* combination simultaneously.
