Allwinnner sunxi SoCs have a low resolution adc (called lradc) which is
specifically designed to have various (tablet) keys (ie home, back, search,
etc). attached to it using a resistor network. This adds a driver for this.
There are 2 channels, currently this driver only supports chan0 since there
are no boards known to use chan1.
This has been tested on an olimex a10s-olinuxino-micro, a13-olinuxino, and
a20-olinuxino-micro.

Changes in v2:
-Change devicetree bindings to use a per key subnode, like gpio-keys does
Changes in v3:
-Handle keyup irq flag before irqdown, in case we get both at once
Thank you for making changes. Can you please tell me if the driver still
works if you drop the patch below on top of it? The changes are:
- split DT parsing into a separate function;
- make sure keymap is not empty;
- change 'ret' variable to 'error';
The proposed changes look good, and I've given them a test-spin and everything
still works fine.
Thanks & Regards,
Hans
