    Subject[PATCH V4 3/4] dt-bindings: serial: add a new compatible string for SC9860
    Date
    SC9860 use the same serial device which SC9836 uses, so added a new
    compatible string to support SC9860 as well, also added an example
    of how to describe this serial device in DT.

    Required properties:
    -- compatible: must be "sprd,sc9836-uart"
    +- compatible: must be one of:
    + * "sprd,sc9836-uart"
    + * "sprd,sc9860-uart", "sprd,sc9836-uart"
    +
    - reg: offset and length of the register set for the device
    - interrupts: exactly one interrupt specifier
    - clocks: phandles to input clocks.
    +
    +Example:
    + uart0: serial@000000 {
    + compatible = "sprd,sc9860-uart",
    + "sprd,sc9836-uart";
    + reg = <0x000000 0x100>;
