Subject: [PATCH V7 1/5] dt-bindings: mfd: pm8008: Add pm8008 regulators
Add regulators and their supply nodes. Add separate compatible
"qcom,pm8008-regulators" to differentiate between pm8008 infra
and pm8008 regulators mfd devices.
Signed-off-by: Satya Priya <quic_c_skakit@...cinc.com>

Changes in V2:
- As per Rob's comments changed "pm8008[a-z]?-regulator" to
"^pm8008[a-z]?-regulators".
Changes in V3:
- Fixed bot errors.
- As per stephen's comments, changed "^pm8008[a-z]?-regulators$" to
"regulators".
Changes in V4:
- Changed compatible string to "qcom,pm8008-regulators"
Changes in V5:
- Remove compatible for regulators node.
- Move supply nodes of the regulators to chip level.
Changes in V6:
- No changes.
Changes in V7:
- Removed the intermediate regulators node and added ldos
directly under mfd node.
