Texas Instrument's TPS65910 PMIC contains 3 buck DC-DC converts, one boost DC-DC converter and 8 LDOs. This patch implements driver model support for the TPS65910 PMIC and its regulators making the get/set API for regulator value/enable available. This patch depends on the patch "am33xx: Add a function to query MPU voltage in uV" to build correctly. For boards relying on the DT include file tps65910.dtsi the v3 patch "power: extend prefix match to regulator-name property" and an appropriate regulator naming is also required.
