On the back of that it has been suggested that we should reduce the number of compatible strings in our dt_compat structure. After subsequent discussion with Arnd Bergmann the conclusion was to list entries by platform as opposed to by board. The other suggestion was to use a single string which would cover all supported platforms, but any wildcard entries would include unsupported chipsets, such as the u5500 and potential new chips which no not yet have DT functionality. Hence, the best solution which encompasses all supported platforms, but no unsupported ones was to list the currently enabled four chipsets; u8500, u8540, u9500 and u9540 instead.
