* BCM63xx UART Required properties: - compatible: "brcm,bcm6345-uart" - reg: The base address of the UART register bank. - interrupts: A single interrupt specifier. - clocks: Clock driving the hardware; used to figure out the baud rate divisor. Optional properties: - clock-names: Should be "refclk". Example: uart0: serial@14e00520 { compatible = "brcm,bcm6345-uart"; reg = <0x14e00520 0x18>; interrupt-parent = <&periph_intc>; interrupts = <2>; clocks = <&periph_clk>; clock-names = "refclk"; }; clocks { periph_clk: periph_clk@0 { compatible = "fixed-clock"; #clock-cells = <0>; clock-frequency = <54000000>; }; };
