7d8d862523 Input: gpio-keys - clean up device tree binding example
Drop #address-cells and #size-cells, which are not required by the
gpio-keys binding documentation, as button sub-nodes are not devices.

Rename sub-nodes to avoid new dtc unit address warnings when copied.

While at it, adopt the dashes convention for the node name.

c4dc5f8c95 Input: gpio-keys - allow setting input device name in DT
Allow specifying name if input device via device tree property. This helps
userspace code to get name and perform proper event to key mapping in some
cases (for example, on Android).

71a0151c5c Documentation: devicetree: fix reference to legacy wakeup properties
This patch marks all the reference to the legacy wakeup bindings
and replaces them with the standard "wakeup-source" property.

All these legacy property are also listed under a separate section in
the generic wakeup-source binding document.

99b4ffbd84 Input: gpio_keys[_polled] - change name of wakeup property
Wakeup property of device is not Linux-specific, it describes intended
system behavior regardless of the OS being used. Therefore let's drop
"linux," prefix, and, while at it, use the same name as I2C bus does:
"wakeup-source".

We keep parsing old name to keep compatibility with old DTSes.

97d86e07b7 Input: gpio_keys - allow separating gpio and irq in device tree
This change allows specify interrupt for buttons separately form gpio,
potentially allowing to form several "clusters" of buttons on
different interrupts.

Button defined without both gpio and irq in device tree is a hared error
instead of a warning now.
