Too many drivers use all sorts of different types, I've given up hope of changing drivers to agree on the same type here. Basically you can think of 'void __iomem *' as the magic keyword for something that gets returned from ioremap, can take an integer offset and gets passed into readb/readw/readl/write..., but any other assumption beyond that is dangerous.
