Yes, I forgot update this list, I will update it in the future.

There isn't any complain about this compatible when I run
dt_binding_check and dtb_check.
Here is the commands which I used:
1. make ARCH=arm64 dtbs_check W=1
2. make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- DT_CHECKER_FLAGS=-m
dt_binding_check
DT_SCHEMA_FILES=Documentation/devicetree/bindings/pinctrl/qcom,sm4450-tlmm.yaml
