Some cros ECs support a front proximity MKBP event via 'EC_MKBP_FRONT_PROXIMITY'. Add a DT binding to document this feature via a node that is a child of the main cros_ec device node. Devices that have this ability will describe this in firmware.

Google's ChromeOS EC sometimes has the ability to detect user proximity.
|
|
This is implemented on the EC as near/far logic and exposed to the OS
|
|
via an MKBP switch bit.
