I understand your arguments. If Wolfgang will not reject my pull
request, I'm fine with it. Could you please use something like:

struct clcd_regs {
	u32 tim0;
	u32 tim1;
	u32 tim2;
	u32 tim3;
	u32 ubas;
	u32 lbas;
#if !defined(CONFIG_ARCH_VERSATILE) && !defined(CONFIG_ARCH_REALVIEW)
	u32 ienb;
	u32 cntl;
#else
/*
 * Someone rearranged these two registers on the Versatile
 * platform...
 */
	u32 cntl;
	u32 ienb;
#endif
	u32 stat;
	u32 intr;
	u32 ucur;
	u32 lcur;
	u32 res[0x74];
	u32 pal;
};

in the amba_clcd header?

And then in the code something like:

	struct clcd_regs *regs;
	...

	...
	regs = (struct clcd_regs *)NOMADIK_CLCDC_BASE;
	...
	writel(regval->tim0, &regs->tim0);
	...

Thanks,
Anatolij
