Mediatek MT6357 Regulator Driver
|
|
|
|
Required properties:
|
|
- compatible: "mediatek,mt6357-regulator"
|
|
- mt6357regulator: List of regulators provided by this controller. It 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.
|
|
|
|
Optional properties in the sub-node:
|
|
- mediatek,oc-irq-enable-delay-ms: Time to delay in milliseconds between
|
|
re-enable over current interrupt after it triggered and be disabled.
|
|
If it's not specified, the default value of this property is set to 10.
|
|
|
|
The valid names for regulators are:
|
|
BUCK:
|
|
buck_vs1, buck_vmodem, buck_vcore, buck_vproc, buck_vpa
|
|
LDO:
|
|
ldo_vfe28, ldo_vxo22, ldo_vrf18, ldo_vrf12, ldo_vefuse, ldo_vcn33_bt,
|
|
ldo_vcn33_wifi, ldo_vcn28, ldo_vcn18, ldo_vcama, ldo_vcamd, ldo_vcamio,
|
|
ldo_vldo28, ldo_vsram_others, ldo_vsram_proc, ldo_vaux18, ldo_vaud28,
|
|
ldo_vio28, ldo_vio18, ldo_vdram, ldo_vmc, ldo_vmch, ldo_vemc, ldo_vsim1,
|
|
ldo_vsim2, ldo_vibr, ldo_vusb33
