[PATCH 04/29] dt-bindings:iio:humidity:dht11 yaml conversion

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

The conversion is straight forward, but leaves an open question.
The compatible for this device has never had a vendor. I suspect
this because it is non-obvious who actually makes the module. It is
resold by numerous vendors and it may be that there is no single vendor
of the parts they are using.  If anyone has any more info on the
vendor, please let me know and we can add a more informative
compatible.
