Simon Glass	e160f7d430	dm: core: Replace of_offset with accessor ... At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

Michal Simek	d79ac32478	i2c: muxes: Add support for TI PCA954X mux ... Add support for common TI i2c mux which is available on ZynqMP zcu102 board. DM i2c mux core code is selecting/deselecting bus before/after every command is performed that's why only one channel is active at a time. That's also the reason why deselect is just disable all available channels.
