I don't know what the current policy is on allocating major/minor numbers,
but I'm sure you cannot just reuse one that is already used.
I agree, why are you trying to create a new tty device name?  Can't you
use the existing ttyS name and minor number as you will not have any
other type of serial device on this system?
This would be an issue on systems that either accept plug-in cards
such as PCMCIA/CardBus/PCI or have additional off SoC IO spaces
where 8250 compatible UARTS could live.
I thought these were set-top box systems that couldn't accept any
plug-in cards or anything else?  This is a SoC, right?

thanks,
