Sort these and add a type so it is clear how to set the value. Add a note about usage to the top. Correct the 'no-keyboard' binding which is missing a prefix.
Signed-off-by: Simon Glass sjg@chromium.org Reviewed-by: Marcel Ziswiler marcel.ziswiler@toradex.com --- Note that some uses a u-boot prefix and some don't. Once [1] is applied we may want to update this to always use the prefix, or never. Another option would be to call the node u-boot,config. and drop the prefix. This has the advantage of complying with the devicetree spec, at little cost.
