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 out. 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. [1] https://lkml.org/lkml/2017/2/14/655 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 initialized. - 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 h/w. - '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.
