the devices explicitly. Please see Documentation/i2c/instantiating-devices for
details.
WARNING: Do not access chip registers using the i2cdump command, and do not use
any of the i2ctools commands on a command register (0xa5 to 0xac). The chips
supported by this driver interpret any access to a command register (including
read commands) as request to execute the command in question. This may result in
power loss, board resets, and/or Flash corruption. Worst case, your board may
turn into a brick.
