336 Caution! at91rm9200, at91sam9261, at91sam9260, at91sam9263 devices
337 don't have clock stretching in transmission mode. For that reason,

1047 This supports the PCF8584 ISA bus I2C adapter. Say Y if you own
1048 such an adapter.

1050 This support is also available as a module. If so, the module
1051 will be called i2c-elektor.

1065 This device is almost undetectable and using this driver on a
1066 system which doesn't have this device will result in long
1067 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
1068 time). If unsure, say N.

1080 If you say yes here you get an I2C bus that will tunnel i2c commands
1081 through to the other side of the ChromeOS EC to the i2c bus
1082 connected there. This will work whatever the interface used to
1083 talk to the EC (SPI, I2C or LPC).
