| - reg: The base address of the UART register bank. |
| |
| - interrupts: |
| index 0: an interrupt specifier for the UART controller itself |
| index 1: optional, an interrupt specifier with edge sensitivity on Rx pin to |
| support Rx in-band wake up. If one would like to use this feature, |
| one must create an addtional pinctrl to reconfigure Rx pin to normal |
| GPIO before suspend. |
| |
| - clocks : Must contain an entry for each entry in clock-names. |
| See ../clocks/clock-bindings.txt for details. |
| - clock-names: |
| - "baud": The clock the baudrate is derived from |
| - "bus": The bus clock for register accesses (optional) |
| |
| For compatibility with older device trees an unnamed clock is used for the |
| baud clock if the baudclk does not exist. Do not use this for new designs. |
| |
| Example: |
| |
| uart0: serial@11006000 { |
| compatible = "mediatek,mt6589-uart", "mediatek,mt6577-uart"; |
| reg = <0x11006000 0x400>; |
| interrupts = <GIC_SPI 51 IRQ_TYPE_LEVEL_LOW>, |
| <GIC_SPI 52 IRQ_TYPE_EDGE_FALLING>; |
| clocks = <&uart_clk>, <&bus_clk>; |
| clock-names = "baud", "bus"; |
| pinctrl-names = "default", "sleep"; |
| pinctrl-0 = <&uart_pin>; |
| pinctrl-1 = <&uart_pin_sleep>; |
| }; |
