| Tom Rini | 53633a8 | 2024-02-29 12:33:36 -0500 | [diff] [blame] | 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) |
| 24 | |
| 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 | }; |
