Indeed. These names come from Qualcomm's v15, but I should have caught that. Thanks. Johan

Only trying to provide some background rationale.

Only trying to provide > some background rationale. I know, but if datasheet calls this "yellow_pony_!!!#1l33t-supply" we still won't use datasheet names directly, so s/_/-/. That's also W=2 warning.

Rework the pm8008 binding by dropping internal details like register offsets and interrupts and by adding the missing regulator and temperature alarm properties. Note that child nodes are still used for pinctrl and regulator configuration. Also note that the pinctrl state definition will be extended later and could eventually also be shared with other PMICs (e.g. by breaking out bits of qcom,pmic-gpio.yaml).
