Laxman Dewangan 9394b80c35 regulator: tps6586x: add support for SYS rail
Device have SYS rail which is always ON. It is system power bus. LDO5
and LDO_RTC get powered through this rail internally. Add support for
this rail and make the LDO5/LDO_RTC supply by it. Update document
accordingly.

[swarren: Instantiate the sys regulator from board-harmony-power.c to
 avoid regression.]

Mark Brown c172708d38 regulator: core: Use a struct to pass in regulator runtime configuration
Rather than adding new arguments to regulator_register() every time we
want to add a new bit of dynamic information at runtime change the function
to take these via a struct. By doing this we avoid needing to do further
changes like the recent addition of device tree support which required each
regulator driver to be updated to take an additional parameter.

The regulator_desc which should (mostly) be static data is still passed
separately as most drivers are able to configure this statically at build
time.

Rajendra Nayak 2c043bcbf2 regulator: pass additional of_node to regulator_register()
With device tree support for regulators, its needed that the
regulator_dev->dev device has the right of_node attached.
To be able to do this add an additional parameter to the
regulator_register() api, wherein the dt-adapted driver can
then pass this additional info onto the regulator core.

Change the interface used by set_voltage() to report the selected value
to the regulator core in terms of a selector used by list_voltage().
This allows the regulator core to know the voltage that was chosen
without having to do an explict get_voltage(), which would be much more
expensive as it will generally access hardware.
