Yes, sdm845.dtsi uses 4 entries and rest 1.

Boolean comes under flag in types.yaml
definitions:
flag:
oneOf:
- type: boolean
const: true
- type: 'null'
I have seen other boolean properties(spi-cpol, spi-cpha and bunch of
others) using type flag. I think we should keep flag here.

I missed qcom,ee. Will add in v3.
For clocks and clock-names , there are two platforms(msm8996.dtsi,
sdm845.dtsi) where these properties are missing. And I don't want to add
some random values. Shall I skip them here? and let board owners add
them later.
