The 'wakeup-source' property is used by many devicetree files and is also supported by the tsc2007_core driver. Document it to avoid the following dt-schema warning: 'wakeup-source' does not match any of the regexes: '^pinctrl-[0-9]+$' Signed-off-by: Fabio Estevam <festevam@gmail.com> Acked-by: Conor Dooley <conor.dooley@microchip.com> Link: https://lore.kernel.org/r/20250822213245.125901-1-festevam@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
