Say yes here to add support for NXP PF1550. This is a companion Power
|
||||
Management IC with regulators, onkey, and charger control on chip.
|
||||
This driver provides common support for accessing the device;
|
||||
additional drivers must be enabled in order to use the functionality
|
||||
of the device.
|
||||
|
||||
This driver can also be built as a module and if so will be called
|
||||
pf1550.
