My problem is, I am doing something like this:

s32 pruss_writel_multi(struct device *dev, u32 offset,
u32 *pdatatowrite, u16 wordstowrite)
{
struct pruss_priv *pruss = dev_get_drvdata(dev->parent);
u32 __iomem *paddresstowrite;
u16 i;

paddresstowrite = pruss->ioaddr + offset;

for (i = 0; i < wordstowrite; i++)
iowrite32(*pdatatowrite++, paddresstowrite++);

return 0;
}

So, if I make paddresstowrite as void, it will not work. The above
implementation does not generate any sparse errors though.

Yes, that why I can work with readb_multi even if I have void __iomen *.

But, how do I solve this problem. In the above function, I must use u32 __iomem *
