Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

menuconfig REGULATOR
	bool "Voltage and Current Regulator Support"
	select LINEAR_RANGES
	help
	  Generic Voltage and Current Regulator support.

	  This framework is designed to provide a generic interface to voltage
	  and current regulators within the Linux kernel. It's intended to
	  provide voltage and current control to client or consumer drivers and
	  also provide status information to user space applications through a
	  sysfs interface.

	  The intention is to allow systems to dynamically control regulator
	  output in order to save power and prolong battery life. This applies
	  to both voltage regulators (where voltage output is controllable) and
	  current sinks (where current output is controllable).

	  This framework safely compiles out if not selected so that client
	  drivers can still be used in systems with no software controllable
	  regulators.

	  If unsure, say no.


if REGULATOR

config REGULATOR_DEBUG
	bool "Regulator debug support"
	help
	  Say yes here to enable debugging support.

config REGULATOR_FIXED_VOLTAGE
	tristate "Fixed voltage regulator support"
	help
	  This driver provides support for fixed voltage regulators,
	  useful for systems which use a combination of software
	  managed regulators and simple non-configurable regulators.

config REGULATOR_VIRTUAL_CONSUMER
	tristate "Virtual regulator consumer support"
	help
	  This driver provides a virtual consumer for the voltage and
	  current regulator API which provides sysfs controls for
	  configuring the supplies requested.  This is mainly useful
	  for test purposes.

	  If unsure, say no.

config REGULATOR_USERSPACE_CONSUMER
	tristate "Userspace regulator consumer support"
	help
	  There are some classes of devices that are controlled entirely
	  from user space. Userspace consumer driver provides ability to
	  control power supplies for such devices.

	  If unsure, say no.

config REGULATOR_NETLINK_EVENTS
	bool "Enable support for receiving regulator events via netlink"
	depends on NET
	help
	  Enabling this option allows the kernel to broadcast regulator events using
	  the netlink mechanism. User-space applications can subscribe to these events
	  for real-time updates on various regulator events.

	  If unsure, say no.

config REGULATOR_88PG86X
	tristate "Marvell 88PG86X voltage regulators"
