This patchset adds version detection for the tps6586x mfd family. This is required because some regulator versions use different voltage tables. The regulator driver now uses the right voltage table according to the version. The required voltage for the SM2 converter on the Colibri T20 is 1.8V, however, the device tree states 3.7V right now. Newer versions (>=V1.2) of the Colibri T20 module use the TPS658643, whereas old ones (<V1.2) use the TPS658623. Both of them have a different voltage table for SM2. The current device tree contains a voltage which results in 1.8V for the older TPS658623. Since the regulator driver has correct voltage tables for both regulator versions now, we can request the correct 1.8V from the device tree. Tested on Colibri T20 V1.1 and V1.2.
