H A D | i2c-sysfs.rst | 12 kernel abstracts the MUX channels into logical I2C bus numbers. However, there 13 is a gap of knowledge to map from the I2C bus physical number and MUX topology 14 to logical I2C bus number. This doc is aimed to fill in this gap, so the 38 so you can find the I2C Sysfs under ``/sys/bus/i2c/devices`` 43 the first number is I2C bus number, and the second number is I2C address. 47 blueline:/sys/bus/i2c/devices $ ls 51 ``i2c-2`` is an I2C bus whose number is 2, and ``2-0049`` is an I2C device 52 on bus 2 address 0x49 bound with a kernel driver. 59 (Physical) I2C Bus Controller 63 physical I2C bus controllers.
