node /dev/ttyCPM2 not created

hi,

I've configured SCC1 to be serial uart driver.
(in addition to SMC1 & SMC2 that were already configured
as UARTs).

Now I can see these defines in .config file:
CONFIG_SERIAL_CPM_SCC1=y
CONFIG_SERIAL_CPM_SMC1=y
CONFIG_SERIAL_CPM_SMC2=y

When the kernal starts I see these log messages:
ttyCPM0 at MMIO 0xc505ca80 (irq = 17) is a CPM UART

ttyCPM1 at MMIO 0xc5060a90 (irq = 16) is a CPM UART

ttyCPM2 at MMIO 0xc5064a00 (irq = 40) is a CPM UART



But when I list the devices:
[root@urm dev]# ll ttyCPM*

crw-rw-rw-    1 root     root     204,  46 Dec 31 17:00 ttyCPM0

crw-rw-rw-    1 root     root     204,  47 Dec 31 17:00 ttyCPM1


I can't see ttyCPM2.

Does anyone know what I'm missing? or what do I need to configure
in order to have: /dev/ttyCPM2 ?

Thanks,
Liran.
