I'm not sure I understand this. You're asking the regulator to output ranges not voltages and you're setting multiple overlapping ranges for each VSEL. > Based on voltage increment requirements for a given application, this > table can be tune more.

This just seems like it makes the driver configuration much more complex and restricts the ability of the system to adapt itself to what's happening at runtime. What I'd expect to see is nothing but the GPIOs and their default state (since sadly we can't read back from output GPIOs with gpiolib) being specified. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
