[PATCH 2/3] dt-bindings: iio: Add cros ec proximity yaml doc
From: Stephen Boyd <hidden>

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.
