This patch adds support for the Mule I2C multiplexer.

Mule is an mcu that emulates a set of i2c devices which are reacheable

reachable

through an i2c-mux.

The emulated devices share a single i2c address with the mux itself where
the requested register is what determines which logic is executed (mux or
device).
Just to be sure, we need a complete binding for the MCU. Is this the
only thing the MCU does?


Currently that is all the MCU does. We plan to add more features to the MCU firmware: Buzzer over i2c, watchdog over i2c ...


Best regards
