- * The driver init all necessary registers to place the PSC in uart mode without

- *
- * The idx field must be equal to the PSC index (e.g. 0 for PSC1, 1 for PSC2,
- * and so on). So the PSC1 is mapped to /dev/ttyPSC0, PSC2 to /dev/ttyPSC1 and
- * so on. But be warned, it's an ABSOLUTE REQUIREMENT ! This is needed mainly
