• Spreadtrum serial UART

Required properties:

• compatible: must be one of:

  • “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@0 {
compatible = “sprd,sc9860-uart”,
“sprd,sc9836-uart”;
reg = <0x0 0x100>;
interrupts = <GIC_SPI 2 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&ext_26m>;
};
