Subject: [PATCH 4.1 193/267] ARM: dts: mx23: fix iio-hwmon support

4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stefan Wahren <stefan.wahren@...e.com>

commit e8e94ed6285428ab780cd7b0df4622f71eceb39e upstream.

In order to get iio-hwmon support, the lradc must be declared as an
iio provider. So fix this issue by adding the #io-channel-cells property.
