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.
