This is more in line with what tcpm does and will be needed
to avoid recursive dependency like
> drivers/power/supply/Kconfig:2:error: recursive dependency detected!
drivers/power/supply/Kconfig:2: symbol POWER_SUPPLY is selected by TYPEC_TPS6598X
drivers/usb/typec/Kconfig:64: symbol TYPEC_TPS6598X depends on REGMAP_I2C
drivers/base/regmap/Kconfig:19: symbol REGMAP_I2C is selected by CHARGER_ADP5061
drivers/power/supply/Kconfig:93: symbol CHARGER_ADP5061 depends on POWER_SUPPLY
For a resolution refer to Documentation/kbuild/kconfig-language.rst
subsection "Kconfig recursive dependency limitations"
when selecting POWER_SUPPLY.

The QCOM SPMI typec driver handles the role and orientation detection, and
notifies client drivers using the USB role switch framework. It registers
as a typec port, so orientation can be communicated using the typec switch
APIs. The driver also attains a handle to the VBUS output regulator, so it
can enable/disable the VBUS source when acting as a host/device.

STMicroelectronics USB Type-C port controllers use I2C interface to
configure, control and read the operation status of the device. All ST USB
Type-C port controllers are based on the same I2C register map. That's why
this driver can be used with all ST USB Type-C ICs.
Some ST USB Type-C port controllers are Dual Role Port (DRP), only Sink or
Source, some supports USB Power Delivery. This can be configured through
connector device tree bindings.
This driver is a basic Type-C port controller driver, with no power
delivery support. It allows to configure ST USB Type-C port controller.
Interrupt is supported and enables CC connection events, to detect
attach and detach and update Type-C subsystem accordingly as well as usb
role switch.
ST USB Type-C port controller can be supplied in three different ways
depending on the target application:
- through VDD pin only (so VDD is the main supply)
- through VSYS pin only (so VSYS is the main supply)
- through VDD and VSYS pins.
When both VDD and VSYS power supplies are present, the low power supply
VSYS is selected as main supply when VSYS voltage is above 3.1V, else
VDD is selected as main supply.
In case of Source or Dual port type, if VDD supply is present, it has to be
enabled in case of Source power role to provide Vbus. When interrupt
support is available, VDD supply is dynamically managed upon attach/detach
interrupt. When there is no interrupt support, VDD supply is enabled by
default.

When I switched on USB role switching for the tps6598x I completely forgot
to add the Kconfig dependency.
Ensure USB_ROLE_SWITCH is selected to prevent the typs6598x driver being
compiled in but the role-switch driver being compiled as a module, leading
to link error.

This commit adds a power_supply class instance to represent a
PD source's voltage and current properties. This provides an
interface for reading these properties from user-space or other
drivers.
For PPS enabled Sources, this also provides write access to set
the current and voltage and allows for swapping between standard
PDO and PPS APDO.
As this represents a superset of the information provided in the
fusb302 driver, the power_supply instance in that code is removed
as part of this change, so reverting the commit titled
'typec: tcpm: Represent source supply through power_supply class'

UCSI - USB Type-C Connector System Software Interface - is a
specification that defines set of registers and data
structures for controlling the USB Type-C ports. It's
designed for systems where an embedded controller (EC) is in
charge of the USB Type-C PHY or USB Power Delivery
controller. It is designed for systems with EC, but it is
not limited to them, and for example some USB Power Delivery
controllers will use it as their direct control interface.
With UCSI the EC (or USB PD controller) acts as the port
manager, implementing all USB Type-C and Power Delivery state
machines. The OS can use the interfaces for reading the
status of the ports and controlling basic operations like
role swapping.
The UCSI specification highlights the fact that it does not
define the interface method (PCI/I2C/ACPI/etc.).
Therefore the driver is implemented as library and every
supported interface method needs its own driver. Driver for
ACPI is provided in separate patch following this one.
The initial driver includes support for all required
features from UCSI specification version 1.0 (getting
connector capabilities and status, and support for power and
data role swapping), but none of the optional UCSI features
(alternate modes, power source capabilities, and cable
capabilities).

The purpose of USB Type-C connector class is to provide
unified interface for the user space to get the status and
basic information about USB Type-C connectors on a system,
control over data role swapping, and when the port supports
USB Power Delivery, also control over power role swapping
and Alternate Modes.
