-/* Platform device Usage :
- *
- * Since PSCs can have multiple function, the correct driver for each one
- * is selected by calling mpc52xx_match_psc_function(...). The function
- * handled by this driver is "uart".
- *
- * The driver init all necessary registers to place the PSC in uart mode without
- * DCD. However, the pin multiplexing aren't changed and should be set either
- * by the bootloader or in the platform init code.
- *
- * 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
- * fpr the console code : without this 1:1 mapping, at early boot time, when we
- * are parsing the kernel args console=ttyPSC?, we wouldn't know which PSC it
- * will be mapped to.
