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.

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.

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.

which has control logic to change the supply voltage via I2C to achieve

We use regmap regulator ops to enable/disable and check if regulator
is enabled for various SMPS. However, these depend on valid
enable_reg, enable_mask and enable_value in regulator descriptor.

("regulator: palmas: Fix SMPS enable/disable/is_enabled"), populate the
same for TPS65917 SMPS registration. LDO definitions are already in
place.
