This is a note to let you know that I've just added the patch titled
dt-bindings: iio: Add cros ec proximity yaml doc
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-next branch.
The patch will show up in the next release of the linux-next tree

Subject: dt-bindings: iio: Add cros ec proximity yaml doc
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.
