2014-07-31regulator: tps65090: Set voltage for fixed regulatorsJavier Martinez Canillas
According to the tps65090 data manual [0], the DCDC1 and DCDC2 step-down converters and the LDO's have a fixed output voltage. Add this information to the driver since these fixed regulators can be used as parent input supply for switches that don't have an output voltage defined. So the regulator core needs to fetch the FET parent output voltage if the child voltage is queried.

2014-07-29regulator: core: Allow to get voltage count and list from parentJavier Martinez Canillas
Load switches are modeled as regulators but they just provide the voltage of their parent input supply. So, the drivers for these switches usually neither provide a .list_voltage handler not set a .n_voltages count. But there is code in the kernel that assumes that all regulators should be able to provide this information (e.g: cpufreq and mmc subsystems). If the voltage count and list are not available for a regulator and it has a parent input supply, then use the parent values.

So the drivers for these switches usually don't provide a .get_voltage function handler but there is code in the kernel that assumes that all regulators should be able to provide its current voltage rail.

2014-07-25regulator: Add helpers for low-level register accessTuomas Tynkkynen
Add helper functions that allow regulator consumers to obtain low-level details about the regulator hardware, like the voltage selector register address and such. These details can be useful when configuring hardware or firmware that want to do low-level access to regulators, with no involvement from the kernel. The use-case for Tegra is a voltage-controlled oscillator clocksource which has control logic to change the supply voltage via I2C to achieve a desired output clock rate.
