Though the keyboard and other driver will continue to support the legacy "gpio-key,wakeup", "linux,wakeup" boolean property to enable the wakeup source, "wakeup-source" is the new standard binding. This patch replaces all the legacy wakeup properties with the unified "wakeup-source" property in order to avoid any futher copy-paste duplication.
