title: Access GPIO Hog input value
body: <p>I'm trying to have some GPIO pins on my SoC board available by default at boot.  I've run across the gpio-hog property in the device tree documentation <a href="http://elixir.free-electrons.com/linux/v4.9.41/source/Documentation/devicetree/bindings/gpio/gpio.txt" rel="nofollow noreferrer">here</a>, and I have my 'hogged' pin visible in userspace.  How can I see the value of that pin?  It's configured as an input.</p>
