*st-asc(Serial Port) Required properties: - compatible : Should be "st,asc". - reg, reg-names, interrupts, interrupt-names : Standard way to define device resources with names. look in Documentation/devicetree/bindings/resource-names.txt Optional properties: - st,hw-flow-ctrl bool flag to enable hardware flow control. - st,force-m1 bool flat to force asc to be in Mode-1 recommended for high bit rates (above 19.2K) Example: serial@fe440000{ compatible = "st,asc"; reg = <0xfe440000 0x2c>; interrupts = <0 209 0>; };
