1 * Spreadtrum serial UART
4 - compatible: must be one of:
6 * "sprd,sc9860-uart", "sprd,sc9836-uart"
8 - reg: offset and length of the register set for the device
9 - interrupts: exactly one interrupt specifier
10 - clock-names: Should contain following entries:
11 "enable" for UART module enable clock,
12 "uart" for UART clock,
13 "source" for UART source (parent) clock.
14 - clocks: Should contain a clock specifier for each entry in clock-names.
15 UART clock and source clock are optional properties, but enable clock
19 - dma-names: Should contain "rx" for receive and "tx" for transmit channels.
20 - dmas: A list of dma specifiers, one for each entry in dma-names.
