(Implemented LE9) RPi Enable dtoverlay=gpio-shutdown to allow a switched power on/off

With a recent release of Raspbian it is possible to power on/off the RPi via a switch.

All that is needed is to have kernel support and then just add dtoverlay=gpio-shutdown to config.txt.

The overlay already exists in /flash/overlay so it just needs to be supported by the kernel.

Details of the overlay are Here

I've test this on Raspbian and it works fine.

You can add gpio_pin=xxx to use another gpio pin but only the default (pin 3) allows a power up.

I'm not too sure if it would work with LE but if it does, I'm sure a lot of RPi users would welcome the ability to safely power off/on their device via switch.

Thanks, seems the gpio_keys (and also the rotary_encoder) modules are missing in LE. Both seem to be very useful and we'll be including them in LE 9.

so long,
