-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>;
-};
