Subject: [PATCH v7 1/3] regulator: dt-bindings: mt6323: Convert to DT schema
Convert the MT6323 regulator binding from the old text-based format to
the new DT schema style. The property "regulator-name" has been added
as required property to reflect current usage in mt6323.dtsi.
Examples have been streamlined and relocated to the parent schema file:
mfd/mediatek,mt6397.yaml.
Update maintainer and submitter information with new entries from MediaTek.
The reference document cited in "mediatek,mt7530.yaml" has been updated
to point to this new DT schema file

Changes for v1 and v2:
- This is the first version of converting mt6323-regulator.
This is because converting mt6323-regulator together
with mfd/mediatek,mt6397.yaml, so we've create a patch set
instead of single patch for each skydives.
- This patch has been made base on linux-next/master git repo.
Changes for v3:
- Rebased on linux-next/master git repo near next-20240906.
- Added 'regulator-name' to 'requried' property to reflect current usage.
- replace ^(buck_)? and ^(ldo_)? to ^buck_ and ^ldo_ prefix.
- Update file name of 'mediatek,mt6323-regulator.yaml' in
'mediatek,mt7530.yaml'
Changes for v4:
- No change.
Changes for v5:
- Add "Reviewed-by" in commit message. Thanks for the review!
- Remove a blank line at EOF whcih causes whitespace warning
when 'git am' the patch.
Changes for v6:
- No change.
Change for v7:
- Add "Acked-by" tag, Thanks for the review.

-All voltage regulators are defined as subnodes of the regulators node. A list
-of regulators provided by this controller are defined as subnodes of the
-PMIC's node. Each regulator is named according to its regulator type,
-buck_<name> and ldo_<name>. The definition for each of these nodes is defined
-using the standard binding for regulators at
-Documentation/devicetree/bindings/regulator/regulator.txt.
-
-The valid names for regulators are::
-BUCK:
- buck_vproc, buck_vsys, buck_vpa
-LDO:
- ldo_vtcxo, ldo_vcn28, ldo_vcn33_bt, ldo_vcn33_wifi, ldo_va, ldo_vcama,
