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_vcore_sshub, 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_others_sshub, 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, ldo_vcn33_bt, ldo_vcn33_wifi, ldo_vcama2, ldo_vmc, ldo_vldo28, ldo_vaud28,
|
|
ldo_vsim2
