Instantiating I2C device in Linux userspace
linux/Documentation/i2c/instantiating-devices
File new_device takes 2 parameters: the name of the I2C device (a string) and the address of the I2C device (a number, typically expressed in hexadecimal starting with 0x, but can also be expressed in decimal.)echo 24c64 0x51 > /sys/bus/i2c/devices/i2c-0/new_device
File delete_device takes a single parameter: the address of the I2C device. As no two devices can live at the same address on a given I2C segment, the address is sufficient to uniquely identify the device to be
deleted.
Example:
# echo eeprom 0x50 > /sys/bus/i2c/devices/i2c-3/new_device
echo 0x51 > /sys/bus/i2c/devices/i2c-0/delete_device
