Currently we do have only one EVM for AM3517 available in the market and which doesn't support DSI interface, so there is no DSI power source available or required. Also the power chip being used is low cost which doesn't have these many sources available. At-least for our internal release, the quick solution I did is, I have encapsulated the regulator_* API calls under !cpu_is_omap3517() && !cpu_is_omap3505(). The ideal solution would be to take the input from board hook up part for power supply also, that way we can support OMAP3 based various EVM's where we have different power chip. Since I am busy with some other high priority issues, I will be able to take this up after this only.
