+         This provides an I2C bus that will tunnel i2c commands through to
+         the other side of the Chrome OS EC to the I2C bus connected there.
+         This will work whatever the interface used to talk to the EC (SPI,
+         I2C or LPC). Some Chromebooks use this when the hardware design
+         does not allow direct access to the main PMIC from the AP.
