My bot found errors running 'make dt_binding_check' on your patch:
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/phy/samsung,ufs-phy.example.dt.yaml: example-0: 'ufs-phy@0x15571800' does not match any of the regexes: '.*-names$', '.*-supply$', '^#.*-cells$', '^#[a-zA-Z0-9,+\\-._]{0,63}$', '^[a-zA-Z][a-zA-Z0-9,+\\-._]{0,63}$', '^[a-zA-Z][a-zA-Z0-9,+\\-._]{0,63}@[0-9a-fA-F]+(,[0-9a-fA-F]+)*$', '^__.*__$', 'pinctrl-[0-9]+'
See https://patchwork.ozlabs.org/patch/1258280
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:
pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade
Please check and re-submit.
