What would I use for the > id argument of regulator_get()? Hmm right, I haven't been thinking about this part in too much detail. However, the regulator names are built in following way: - take voltdm name (e.g. mpu_iva) - add "VDD_" in the beginning - capitalize whole thing (results in VDD_MPU_IVA) > What's missing (at least in my mind) is the mapping of devices to > regulators.
