where can find the compatible device info in kernel

[Lemiron24]

I see below code in umd driver: static const struct of_device_id nvdla_of_match[] = { { .compatible = "nvidia,nvdla_os_initial", .data = &nvdla_config_os_initial, }, { .compatible = "nvidia,nvdla_2", .data = &nvdla_config_small, }, { }, };

could you tell me which dts file for this?

thanks
