Sure. I will remove 'qcom,spmi-vib-gen2'.
Should I also keep 'qcom,spmi-vib-gen1' as generic compatible and move
'qcom,pm8916-vib' as its fallback as following?
compatible:
oneOf:
- enum:
- qcom,pm8058-vib
- qcom,pm8921-vib
- items:
- enum:
- qcom,pm8916-vib
- const: qcom,spmi-vib-gen1
- items:
- enum:
- qcom,pmi632-vib
- qcom,pm7250b-vib
- qcom,pm7325b-vib
- qcom,pm7550b-vib
- const: qcom,spmi-vib-gen2
I saw 'qcom,pm8916-vib' has been used in multiple DTS files and updating
it as a fallback will result updating those DTS files as well.
Or please help to suggest if there is any way to keep 'qcom,pm8916-vib'
and 'qcom,spmi-vib-gen1' compatible without updating existing DTS nodes.
Thanks
