Kernel-4.18.0-80.el8_vt8500-uart

  • VIA VT8500 and WonderMedia WM8xxx UART Controller

Required properties:

  • compatible: should be “via,vt8500-uart” (for VIA/WonderMedia chips up to and
    including WM8850/WM8950), or “wm,wm8880-uart” (for WM8880 and later)

  • reg: base physical address of the controller and length of memory mapped
    region.

  • interrupts: hardware interrupt number

  • clocks: shall be the input parent clock phandle for the clock. This should
    be the 24Mhz reference clock.

Aliases may be defined to ensure the correct ordering of the uarts.

Example:
aliases {
serial0 = &uart0;
};

uart0: serial@d8200000 {
    compatible = "via,vt8500-uart";
    reg = <0xd8200000 0x1040>;
    interrupts = <32>;
    clocks = <&clkuart0>;
};
