Ask: How to get UART devicetree node-id mapping program with RT1060

[YMont]

Description
Hi,
I don't know how to mapping devicetree node-id to program declare device pointer name?
As the following example, is it correct? I think I got wrong, but I don't have any idea to fix it.
Thanks a lot.

DTS
zephyr\dts\arm\nxp\nxp_rt10xx.dtsi

lpuart2: uart@40188000 {
			compatible = "nxp,kinetis-lpuart";
			reg = <0x40188000 0x4000>;
			interrupts = <21 0>;
			clocks = <&ccm IMX_CCM_LPUART_CLK 0x68 28>;
			dmas = <&edma0 3 66>, <&edma0 4 67>;
			dma-names = "tx", "rx";
			status = "disabled";
		};

DTSI
zephyr\boards\arm\mimxrt1060_evk\mimxrt1060_evk.dts

&lpuart2 {
	status = "okay";
	current-speed = <115200>;
	pinctrl-0 = <&pinmux_lpuart2>;
	pinctrl-1 = <&pinmux_lpuart2_sleep>;
	pinctrl-names = "default", "sleep";
	clock-frequency = <80000000>;
};

Code Method

#define UART_NODE DT_NODELABEL(lpuart2) // Here, mapping devicetree node-id

struct rt1060_lpuart_config {
	LPUART_Type *base;
	const struct device *clock_dev;
	clock_control_subsys_t clock_subsys;
	clock_ip_name_t clock_ip_name;
	uint32_t clock_ip_src;
	uint32_t baud_rate;
	uint8_t hw_flow_control;
#ifdef CONFIG_UART_INTERRUPT_DRIVEN
	void (*irq_config_func)(const struct device *dev);
#endif
	const struct pinctrl_dev_config *pincfg;
};

static const struct device *const uart_dev = DEVICE_DT_GET(UART_NODE);
const struct rt1060_lpuart_config *clock_config = uart_dev->config;
