I think these are actually package properties, so having the correctly documented in the binding would help a lot understand why we need package properties. Actually using #define like this is probably wrong. You should just have a u32 tx_driver_mv property, and list [140, 160, 180, 200, ... 600] as valid values. The driver should then convert to whatever value it should write into the register. Andrew
