   1 * Device tree bindings for TI TPS61050/61052 Boost Converters
   2
   3 The TP61050/TPS61052 is a high-power "white LED driver". The
   4 device provides LED, GPIO and regulator functionalities.
   5
   6 Required properties:
   7 - compatible:           "ti,tps61050" or "ti,tps61052"
   8 - reg:                  Specifies the I2C slave address
   9
  10 Optional sub-node:
  11
  12 This subnode selects the chip's operational mode.
  13 There can be at most one single available subnode.
  14
  15 - regulator: presence of this sub-node puts the chip in regulator mode.
  16         see ../regulator/regulator.yaml
  17
  18 - led: presence of this sub-node puts the chip in led mode.
  19         Optional properties:
  20         - function : see ../leds/common.txt
  21         - color    : see ../leds/common.txt
  22         - label    : see ../leds/common.txt
  23                         (deprecated)

  25 Example (GPIO operation only):
  26
  27 i2c0 {
  28         tps61052@33 {
  29                 compatible = "ti,tps61052";
  30                 reg = <0x33>;
  31         };
  32 };
  33
  34 Example (GPIO + regulator operation):
  35
  36 i2c0 {
  37         tps61052@33 {
  38                 compatible = "ti,tps61052";
  39                 reg = <0x33>;
  40
  41                 regulator {
  42                         regulator-min-microvolt = <5000000>;
  43                         regulator-max-microvolt = <5000000>;
  44                         regulator-always-on;
  45                 };
  46         };
  47 };
  48
  49 Example (GPIO + led operation):
  50
  51 #include <dt-bindings/leds/common.h>
  52
  53 i2c0 {
  54         tps61052@33 {
  55                 compatible = "ti,tps61052";
  56                 reg = <0x33>;
  57
  58                 led {
  59                         color = <LED_COLOR_ID_WHITE>;
  60                 };
  61         };
  62 };
