32/* Platform device Usage :
33 *
34 * Since PSCs can have multiple function, the correct driver for each one
35 * is selected by calling mpc52xx_match_psc_function(...). The function
36 * handled by this driver is "uart".
37 *
38 * The driver init all necessary registers to place the PSC in uart mode without
39 * DCD. However, the pin multiplexing aren't changed and should be set either
40 * by the bootloader or in the platform init code.
41 *
42 * The idx field must be equal to the PSC index (e.g. 0 for PSC1, 1 for PSC2,
43 * and so on). So the PSC1 is mapped to /dev/ttyPSC0, PSC2 to /dev/ttyPSC1 and
44 * so on. But be warned, it's an ABSOLUTE REQUIREMENT ! This is needed mainly
45 * fpr the console code : without this 1:1 mapping, at early boot time, when we
46 * are parsing the kernel args console=ttyPSC?, we wouldn't know which PSC it
47 * will be mapped to.

54 * list.
55 *
56 * By default, PSC devices are enumerated in the order they are found. However
57 * a particular PSC number can be forces by adding 'device_no = <port#>'
58 * to the device node.
