Hi all, and thanks for your response.
You are correct Guenter. We need to address both i2c- and gpio-based
multiplexers. You and Jean suggested the following solution:
I2C Mux: i2c-N-mux-i2c-XX (chan_id M)
GPIO Mux: i2c-N-mux-gpio-XX (chan_id M)

I'm having the same problem with multiple PCA954x multiplexer
