2012-03-19mfd/ab8500: add version detection and enforcingLinus Walleij
There are currently four different versions of the AB8500 around: AB8500, AB8505, AB9540 and AB8540. Unfortunately: - Some of the chips (AB8500, AB8505, AB9540) cannot read the AB8500_REV_REG register but return errors - Some of them have the same ID value in the hardware register AB8500_REV_REV, for example the first versions of AB8505 and AB9540 have 0xFF in this register - just like the AB8500. So we need to be able to enforce a certain version from the platform. We do this by using the id of the platform device that provides the read/write functions.

Some drivers can detect sub system failures e.g. shared memory driver can detect modem sub system failures. It would be helpful in analyzing these failures if AB register dump is available at that point. This patch adds the API for the drivers to dump AB registers in the kernel log.
