[ts-7000] IRQ on DIO with TS-7400

[Colin Copeland <>]

The TS-7400 manual states you can enable an IRQ on DIO_11.
http://www.embeddedarm.com/Manuals/ts-7400-info.txt

TS-7400 specific registers:
===========================

0x1200_0000: TS-7400 control register
   bit 0 - if set, enables UART #1 on DIO_18 and DIO_19 pins
   bit 1 - if set, enables IRQ on DIO_11 pin
   bit 2 - if set, enables DRQ on DIO_12 pin
   bit 3 - if set, enables 14.7456Mhz clock on DIO_13 pin
   bit 7:4 - reserved

But I'm not sure what irq to ask for with request_irq() in my kernel  
module.
Does anyone know?

Is there a way to write to 0x12000000 in kernel space? I'm used to  
use mmap in user space. Is there an easy way? Can I use a pointer, or  
do I need to use inb/outb or something?
