More or less so. Previous platforms used either qcom-pmic-typec
(sm8150, sm8250) or laptop-specific EC (sdm850 / c630, sc7180 /
aspire1, CrOS). Next platforms (sc8280xp and sm8350, qcm6490) used
pmic-glink and the new way of sending events. I think sc8180x was
really the unfortunate one to use mixed events.
