4 U-Boot's I2C model has the concept of an offset within a chip (I2C target
5 device). The offset can be up to 4 bytes long, but is normally 1 byte,
6 meaning that offsets from 0 to 255 are supported by the chip. This often
7 corresponds to register numbers.
9 Apart from the controller-specific I2C bindings, U-Boot supports a special
10 property which allows the chip offset length to be selected.
13 - u-boot,i2c-offset-len - length of chip offset in bytes. If omitted the
14 default value of 1 is used.
