Currently know interrupt names are "tx" and "rx". - Improve tdm-slots propery description - Improve op-mode property description - Add pinctrl-names and pinctrl-0 properties - Remove #address-cells and #size-cells as they are not needed. - Bracket named interrupts property tuples for uniformity. - Add missing "for" to serial-dir prop in DT bindings doc.
