Ok ... so this is a register address, right? Can you rework this to use the struct-based access?
aka:
struct pxa2xx_udc_regs { uint32_t udccr; uint32_t uicr0; .... };
And then when used, do:
struct pxa2xx_udc_regs *udc_regs;
writel(value, &udc_regs->udccr);
etc.
[...]
btw. you'll usually get better results (and faster review) by CCing me directly, I found your patches accidentally now.
btw2. it'd be cool if someone reworked the PXA stuff to use struct based access altogerther ... see arch/arm/include/mach-mx28/regs*.h for some hints too.
Best regards,
