This is not good since it ties into the global GPIO numberspace and uses gpio_to_desc() to overcome this. Start supporting passing an already initialized GPIO descriptor to the core instead: leaf drivers pick their descriptors, associated directly with the device node (or from ACPI or from a board descriptor table) and use that directly without any roundtrip over the global GPIO numberspace. This looks messy since it adds a bunch of extra code in the core, but at the end of the patch series we will delete the handling of the GPIO number and only deal with descriptors so things end up neat.

Allow calling _regulator_list_voltage() from functions, with regulator_dev argument. This refactoring is needed in order to implement setting voltage of coupled regulators.

It provides better separation of device tree functions from the core and allows other of_functions in of_regulator.c to resolve device_node to regulator_dev. This will be useful for implementation of parsing coupled regulators properties.

And it assumes that if any consumer set suspend voltage, the regulator device should be enabled in the suspend state. And if the suspend voltage of a regulator device for all consumers was set zero, the regulator device would be off in the suspend state. This patch also provides a new function hook to regulator devices for resuming from suspend states.
