+Mediatek MT6323 Regulator Driver
|
|
+
|
|
+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,
|
|
+ ldo_vio28, ldo_vusb, ldo_vmc, ldo_vmch, ldo_vemc3v3, ldo_vgp1, ldo_vgp2,
|
|
+ ldo_vgp3, ldo_vcn18, ldo_vsim1, ldo_vsim2, ldo_vrtc, ldo_vcamaf, ldo_vibr,
|
|
+ ldo_vrf18, ldo_vm, ldo_vio18, ldo_vcamd, ldo_vcamio
