-MediaTek MT6358 Regulator
-
-All voltage regulators provided by the MT6358 PMIC are described as the
-subnodes of the MT6358 regulators 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_vdram1, buck_vcore, buck_vpa, buck_vproc11, buck_vproc12, buck_vgpu,
- buck_vs2, buck_vmodem, buck_vs1
-LDO:
- ldo_vdram2, ldo_vsim1, ldo_vibr, ldo_vrf12, ldo_vio18, ldo_vusb, ldo_vcamio,
- ldo_vcamd, ldo_vcn18, ldo_vfe28, ldo_vsram_proc11, ldo_vcn28, ldo_vsram_others,
- ldo_vsram_gpu, ldo_vxo22, ldo_vefuse, ldo_vaux18, ldo_vmch, ldo_vbif28,
- ldo_vsram_proc12, ldo_vcama1, ldo_vemc, ldo_vio28, ldo_va12, ldo_vrf18,

Convert this from the old style text based binding to the new DT schema style. This will make adding the MT6366 portion easier. The examples have been trimmed down considerably, and the remaining entries now match what is seen in actual device trees, minus some properties that aren't covered by the bindings yet, or don't make sense on their own. The original submitter seems to have left MediaTek, so instead the submitter and maintainer for the MT6366 binding is listed as the maintainer here.
