Select Chromebooks have gpio attached to switches used to cause the

signals to be read from user space.
This functionality has been generalised to provide support for any device
with device tree support which needs to identify a gpio as being used for a
specific task.

Why isn't this in drivers/gpio/ ?
why make it a misc driver?
I thought all the drivers in /drivers/gpio were gpio drivers, rather
than users of the gpio framework. Is that not the case?
Happy to move it if the consensus is that that's the correct place to
put it.
