Okay, but I am getting errors like below during make dtbs_check.

kernel/arch/arm64/boot/dts/qcom/sdm630-sony-xperia-ganges-kirin.dt.yaml: 
pon@800: 'compatible', 'pwrkey', 'reg' do not match any of the regexes: 
'^mode-.*$', 'pinctrl-[0-9]+'

As suggested I have added

allOf:
  - $ref: reboot-mode.yaml#

at the root of binding and also added unevaluatedProperties: false
