   1 Binding for Maxim MAX77802 regulators
   2
   3 This is a part of device tree bindings of MAX77802 multi-function device.
   4 More information can be found in bindings/mfd/max77802.txt file.
   5
   6 The MAX77802 PMIC has 10 high-efficiency Buck and 32 Low-dropout (LDO)
   7 regulators that can be controlled over I2C.
   8
   9 Following properties should be present in main device node of the MFD chip.
  10
  11 Optional node:
  12 - regulators : The regulators of max77802 have to be instantiated
  13   under subnode named "regulators" using the following format.
  14
  15         regulator-name {
  16                 standard regulator constraints....
  17         };
  18         refer Documentation/devicetree/bindings/regulator/regulator.txt

  20 The regulator node name should be initialized with a string to get matched
  21 with their hardware counterparts as follow. The valid names are:
  22
  23         -LDOn   :       for LDOs, where n can lie in ranges 1-15, 17-21, 23-30
  24                         and 32-35.
  25                         example: LDO1, LDO2, LDO35.
  26         -BUCKn  :       for BUCKs, where n can lie in range 1 to 10.
  27                         example: BUCK1, BUCK5, BUCK10.
  28 Example:
  29
  30         max77802@09 {
  31                 compatible = "maxim,max77802";
  32                 interrupt-parent = <&wakeup_eint>;
  33                 interrupts = <26 0>;
  34                 reg = <0x09>;
  35                 #address-cells = <1>;
  36                 #size-cells = <0>;

  38                 regulators {
  39                         ldo11_reg: LDO11 {
  40                                 regulator-name = "vdd_ldo11";
  41                                 regulator-min-microvolt = <1900000>;
  42                                 regulator-max-microvolt = <1900000>;
  43                                 regulator-always-on;
  44                         };

  46                         buck1_reg: BUCK1 {
  47                                 regulator-name = "vdd_mif";
  48                                 regulator-min-microvolt = <950000>;
  49                                 regulator-max-microvolt = <1300000>;
  50                                 regulator-always-on;
