+Hi6220 mtcmos Voltage regulators
+
+Required parent device properties:
+- compatible: Must be "hisilicon,hi6220-mtcmos-driver"
+- hisilicon,mtcmos-steady-us: The time to wait for power steady
+- hisilicon,mtcmos-sc-on-base: address of mtcmos on hi6220 SoC
+
+Required child device properties:
+- regulator-name: The name of mtcmos
+- hisilicon,ctrl-regs: Offset of ctrl-regs
+- hisilicon,ctrl-data: The bit to ctrl the regulator
+
+Example:
+ mtcmos {
+ compatible = "hisilicon,hi6220-mtcmos-driver";
+ hisilicon,mtcmos-steady-us = <10>;
+ hisilicon,mtcmos-sc-on-base = <0xf7800000>;
+ hisilicon,mtcmos-acpu-on-base = <0xf65a0000>;
+
+ mtcmos1: regulator@a1{
+ regulator-name = "G3D_PD_VDD";
+ regulator-compatible = "mtcmos1";
+ hisilicon,ctrl-regs = <0x830 0x834 0x83c>;
+ hisilicon,ctrl-data = <1 0x1>;
+ };
+ mtcmos2: regulator@a2{
+ regulator-name = "SOC_MED";
+ regulator-compatible = "mtcmos2";
+ hisilicon,ctrl-regs = <0x830 0x834 0x83c>;
+ hisilicon,ctrl-data = <2 0x1>;
+ };
+ };
