Jean Delvaref5b728a2008-07-14 22:38:23 +02001049 parallel bus to I2C bus controller.

1051 This driver can also be built as a module. If so, the module
1052 will be called i2c-pca-isa.
1053
1054 This device is almost undetectable and using this driver on a
1055 system which doesn't have this device will result in long
1056 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
1057 time). If unsure, say N.

1068 help
1069 If you say yes here you get an I2C bus that will tunnel i2c commands
1070 through to the other side of the ChromeOS EC to the i2c bus
1071 connected there. This will work whatever the interface used to
1072 talk to the EC (SPI, I2C or LPC).

1091 This exposes the PowerNV platform i2c busses to the linux i2c layer,
1092 the driver is based on the OPAL interfaces.
