dt-bindings: serial: add documentation for Rx in-band wakeup support To support Rx in-band wakeup, one must create an interrupt specifier with edge sensitivity on Rx pin and an addtional pinctrl to reconfigure Rx pin to normal GPIO in sleep state. Driver will switch to sleep mode pinctrl and enable irq wake before suspend and restore to default settings when resuming.
