1186 | This driver is a light version of i2c-parport. It doesn't depend |
1187 | on the parport driver, and uses direct I/O access instead. This | |
1188 | might be preferred on embedded systems where wasting memory for | |
1189 | the clean but heavy parport handling is not an option. The | |
1190 | drawback is a reduced portability and the impossibility to | |
1191 | daisy-chain other parallel port devices. | |

1193 | Don't say Y here if you said Y or M to i2c-parport. Saying M to |
1194 | both is possible but both modules should not be loaded at the same | |
1195 | time. | |
