Which default kernel build configuration is for TX2 in release 32.2.1?

Hello. In the latest kernel sources(kernel-4.9 , release 32.2.1),I could not find the default kernel build configuration ,tegra18_defconfig,which is for TX2 in previous release. So which default kernel build configuration is for TX2 in release 32.2.1? tegra_defconfig ?

In kernel/arch/arm64/configs/ :
defconfig
ranchu64_defconfig
tegra_android_defconfig
tegra_android_defconfig_debug.config
tegra_defconfig
tegra_early_boot_defconfig
tegra_gnu_linux_defconfig
tegra_gnu_linux_defconfig_debug.config
tegra_gnu_linux_early_boot_defconfig
tegra_t186ref_gnu_linux_early_boot_defconfig_debug.config
