usb: typec: STUSB160X should select REGMAP_I2C

2021-11-18T13:04:19+00:00

[ Upstream commit 8ef1e58783b9f55daa4a865c7801dc75cbeb8260 ]

REGMAP_I2C is not a user visible kconfig symbol so driver configs
should not "depend on" it. They should depend on I2C and then
select REGMAP_I2C.

If this worked, it was only because some other driver had set/enabled
REGMAP_I2C.

USB_ROLE_SWITCH also =m.

usb: typec: Add QCOM PMIC typec detection driver

2020-10-09T13:14:43+00:00

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.

usb: typec: add support for STUSB160x Type-C controller family

2020-10-02T13:30:31+00:00

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.

usb: typec: Ensure USB_ROLE_SWITCH is set as a dependency for tps6598x

2020-05-21T07:36:42+00:00

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.
