- Analog devices AS3645A device tree bindings
- The AS3645A flash LED controller can drive two LEDs, one high current
- flash LED and one indicator LED. The high current flash LED can be
- used in torch mode as well.
- Ranges below noted as [a, b] are closed ranges between a and b, i.e. a
- and b are included in the range.
- Please also see common.txt in the same directory.
- Required properties
- ===================
- compatible : Must be "ams,as3645a".
- reg : The I2C address of the device. Typically 0x30.
- #address-cells : 1
- #size-cells : 0
- Required properties of the flash child node (0)
- ===============================================
- reg: 0
- flash-timeout-us: Flash timeout in microseconds. The value must be in
- the range [100000, 850000] and divisible by 50000.
- flash-max-microamp: Maximum flash current in microamperes. Has to be
- in the range between [200000, 500000] and
- divisible by 20000.
- led-max-microamp: Maximum torch (assist) current in microamperes. The
- value must be in the range between [20000, 160000] and
- divisible by 20000.
- ams,input-max-microamp: Maximum flash controller input current. The
- value must be in the range [1250000, 2000000]
- and divisible by 50000.
- Optional properties of the flash child node
- ===========================================
- label : The label of the flash LED.
- Required properties of the indicator child node (1)
- ===================================================
- reg: 1
- led-max-microamp: Maximum indicator current. The allowed values are
- 2500, 5000, 7500 and 10000.
- Optional properties of the indicator child node
- ===============================================
- label : The label of the indicator LED.
- Example
- =======
- as3645a@30 {
- #address-cells: 1
- #size-cells: 0
- reg = <0x30>;
- compatible = "ams,as3645a";
- flash@0 {
- reg = <0x0>;
- flash-timeout-us = <150000>;
- flash-max-microamp = <320000>;
- led-max-microamp = <60000>;
- ams,input-max-microamp = <1750000>;
- label = "as3645a:flash";
- };
- indicator@1 {
- reg = <0x1>;
- led-max-microamp = <10000>;
- label = "as3645a:indicator";
- };
- };
