-* Spreadtrum serial UART
-
-Required properties:
-- 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
-- clock-names: Should contain following entries:
- "enable" for UART module enable clock,
- "uart" for UART clock,
- "source" for UART source (parent) clock.
-- clocks: Should contain a clock specifier for each entry in clock-names.
- UART clock and source clock are optional properties, but enable clock
- is required.
-
-Optional properties:
-- dma-names: Should contain "rx" for receive and "tx" for transmit channels.
-- dmas: A list of dma specifiers, one for each entry in dma-names.
-
-Example:
- uart0: serial@0 {
- compatible = "sprd,sc9860-uart",
- "sprd,sc9836-uart";
- reg = <0x0 0x100>;
- interrupts = <GIC_SPI 2 IRQ_TYPE_LEVEL_HIGH>;
- dma-names = "rx", "tx";
- dmas = <&ap_dma 19>, <&ap_dma 20>;
- clock-names = "enable", "uart", "source";
- clocks = <&clk_ap_apb_gates 9>, <&clk_uart0>, <&ext_26m>;
- };
