H A Di2c-address-translators.rst13 An I2C Address Translator (ATR) is a device with an I2C slave parent
21 An ATR looks similar to an i2c-mux except:
26 The ATR functionality can be provided by a chip with many other features.
27 The kernel i2c-atr provides a helper to implement an ATR within a driver.
29 The ATR creates a new I2C "child" adapter on each child bus. Adding
33 ATR maintains a table of currently assigned alias and uses it to modify
43 | CPU |--A--| ATR |
51 each other. The ATR receives the transactions initiated on bus A and
69 - ATR driver finds slave X is on bus B and has alias 0x20, rewrites
72 - ATR chip detects transaction on address 0x20, finds it in table,
