Hans de Goede 9e1897cb95 extcon: Add LC824206XA microUSB switch driver
Add a new driver for the ON Semiconductor LC824206XA microUSB switch and
accessory detector chip.

ON Semiconductor has an "Advance Information" datasheet available
(ENA2222-D.PDF), but no full datasheet. So there is no documentation
available for the registers.

This driver is based on the register info from the extcon-fsa9285.c driver,
from the Lollipop Android sources for the Lenovo Yoga Tablet 2 (Pro)
830 / 1050 / 1380 models. Note despite the name this is actually a driver
for the LC824206XA not the FSA9285.

This has only been tested on a Lenovo Yoga Tablet 2 Pro 1380 and
using the driver on other setups may require additional work.

So far this driver is only used on x86/ACPI (non devicetree) devs.
Therefor there is no devicetree bindings documentation for this driver's
"onnn,enable-miclr-for-dcp" property since this is not used in actual
devicetree files and the dt bindings maintainers have requested properties
with no actual dt users to _not_ be added to the dt bindings.

tristate "External Connector Class (extcon) support"
help
Say Y here to enable external connector class (extcon) support.
This allows monitoring external connectors by userspace
via sysfs and uevent and supports external connectors with
multiple states; i.e., an extcon that may have multiple
cables attached. For example, an external connector of a device
may be used to connect an HDMI cable and a AC adaptor, and to
host USB ports. Many of 30-pin connectors including PDMI are
also good examples.
