Subject[PATCH v2 0/2] Add support for cros-ec-extcon driver
Dear all,

Now that the drm/rockchip landed it's time to review the extcon cros-ec driver. The
cdn-dp driver uses this extcon driver to get cable status and the presence of display

This driver is based on the one available in chromeos-4.4 kernel but removing
all the USB switch role stuff, as this depends on other infrastructures like
the dwc3 role switch and the Type-C connector.

Note that these patches depends on the following patches to build.


The above patches have been acked and hopefully merged soon in linux-next.

Changes since v1:

Requested by Chanwoo Choi
- Rename files changing _ for -
- Remove the unneeded blank line on bottom of header.
- Remove kobject.h and cros_ec_commands.h includes.
- Remove the debug message as is not necessary.
- Use the tab for indentation instead of space for if sentence.
- Define each variable on different lines when the variables should be
- Remove EXTCON_USB and EXTCON_USB_HOST as are not really used for now.
- Add one blank line to split out between state and property setting.
- Add the author information (header and module)

Requested by Rob Herring
- Remove the Extcon word in the binding and replace it to describe better the
- 'google,extcon-cros-ec' renamed to 'google,extcon-usbc-cros-ec' to indicate
this is USB Type C related.

Enric Balletbo
- As Rob suggested to rename the compatible name to something indicating that
is USB Type C related I also renamed the file names, extcon-cros-ec ->
extcon-usbc-cros-ec, I think it's more clear.
