regulator: dt-bindings: adi,adp5055-regulator: Add adp5055 support
Add documentation for devicetree bindings for ADP5055. The device consists of 3 buck regulators able to connect to high input voltages of up to 18V with no preregulators.

GPIO specifier to enable the GPIO control for each regulator. The

driver supports two modes of enable, hardware only (GPIOs) or software
|

only (Registers). Pure hardware enabling requires each regulator to
|
||||
contain this property. If at least one regulator does not have this,
|
||||
the driver automatically switches to software only mode.
