+description: |
+ 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.

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-testing branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the staging-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. From 19ad93bc82e7d0ea7b02ada623cddfeab20c9046 Mon Sep 17 00:00:00 2001 From: Stephen Boyd <swboyd@chromium.org> Date: Wed, 10 Feb 2021 18:46:00 -0800 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.
