How can I find the source code which imx390_a@1b or imx390_b@1c is use at TX2 R32.2?

How can I find the source code which imx390_a@1b or imx390_b@1c slave address is use at TX2 R32.2?

The imx390_ have two slave address,is 0x1b and 0x1c, they are use same device source code? is right?

Where are I find the use which slave address?

imx390_a@1b {
					def-addr = <0x1a>;
					/* Define any required hw resources needed by driver */
					/* ie. clocks, io pins, power sources */
					clocks = <&tegra_car TEGRA186_CLK_EXTPERIPH1>,
							 <&tegra_car TEGRA186_CLK_PLLP_OUT0>;
					clock-names = "extperiph1", "pllp_grtba";
					mclk = "extperiph1";
					nvidia,gmsl-ser-device = <&ser_a>;
					nvidia,gmsl-dser-device = <&dser>;
				};
				imx390_b@1c {
					def-addr = <0x1a>;
					/* Define any required hw resources needed by driver */
					/* ie. clocks, io pins, power sources */
					clocks = <&tegra_car TEGRA186_CLK_EXTPERIPH1>,
							 <&tegra_car TEGRA186_CLK_PLLP_OUT0>;
					clock-names = "extperiph1", "pllp_grtba";
					mclk = "extperiph1";
					nvidia,gmsl-ser-device = <&ser_b>;
					nvidia,gmsl-dser-device = <&dser>;
				};

hello sensor_test,

you might contact with sensor vendor if you’re asking how to know the device’s slave address.
since these two were same imx390 modules, they could sharing the same kernel drivers for controls.
thanks
