I sent a vendor-prefixes.txt update earlier as part of the UART driver series. 
Greg has it queued in the tty-testing branch of his tty tree 
(https://git.kernel.org/cgit/linux/kernel/git/gregkh/tty.git/commit/?h=tty-testing&id=48c738631753186e0ec7dd0079beffb3a6f4bb5c).

Yes. The interrupt controller uses just a small area in this registers space 
(offsets 0x40 - 0x80). This trouble is that I also need access to the system 
global UC_IRQ_CONTROL register (offset 0x3a4), to configure interrupts channel 
and routing (IRQ/FIQ). I wonder whether register access via syscon is better.

No. There is none.
