Re: [PATCH] Input: cros_ec_keyb: Add support for a front proximity switch

Yes, I understand that on some devices the proximity sensors are not
true sensors but rather on/off signals, potentially derived from a
multitude of sources. However there is still a benefit in exposing them
as IIO proximity devices with limited reporting representing
[near, infinity] range/values. This will mean that userspace needs to
monitor only one set of devices (IIO) instead of both IIO and input, and
will not require constantly expanding EV_SW set to account for
ever-growing number of proximity sensors (lap, palm, general presence,
etc).

Ok, no problem. I think I'll have to spin up a small driver to handle
this as an IIO proximity device and then register the IIO child device
from the cros ec driver. Let me see how that goes.
