1058 help
1059 If you say yes here you get an I2C bus that will tunnel i2c commands
1060 through to the other side of the ChromeOS EC to the i2c bus
1061 connected there. This will work whatever the interface used to
1062 talk to the EC (SPI, I2C or LPC).

1084 This driver can also be built as a module. If so, the module will be
1085 called as i2c-opal.
