No. Our udev and mdev support relies on the devtmpfs filesystem to be enabled
in the kernel and mounted at boot time by the kernel. Buildroot ensures that
this is the case for kernels that it builds (see the following code in
linux/linux.mk), but if you build your kernel outside of Buildroot, it is up to
you to enable those options as well.

        $(if $(BR2_ROOTFS_DEVICE_CREATION_STATIC),,
                $(call KCONFIG_ENABLE_OPT,CONFIG_DEVTMPFS,$(@D)/.config)
                $(call KCONFIG_ENABLE_OPT,CONFIG_DEVTMPFS_MOUNT,$(@D)/.config))

So you must enabled CONFIG_DEVTMPFS and CONFIG_DEVTMPFS_MOUNT in your kernel.
