Interestingly, on a wandboard I did:

diff --git a/configs/wandboard_defconfig b/configs/wandboard_defconfig
index 70b4cf9ffaa3..33d9db56e1cb 100644
--- a/configs/wandboard_defconfig
+++ b/configs/wandboard_defconfig
@@ -72,6 +72,7 @@ CONFIG_PINCTRL_IMX6=y

+CONFIG_DM_SERIAL=y

 CONFIG_DM_THERMAL=y

and it boots fine.
