Describing and referring to LEDs in ACPI
Individual LEDs are described by hierarchical data extension [6] nodes under the
device node, the LED driver chip. The "reg" property in the LED specific nodes
tells the numerical ID of each individual LED output to which the LEDs are
connected. [3] The hierarchical data nodes are named "led@X", where X is the
number of the LED output.
Referring to LEDs in Device tree is documented in [4], in "flash-leds" property
documentation. In short, LEDs are directly referred to by using phandles.
While Device tree allows referring to any node in the tree[1], in ACPI
references are limited to device nodes only [2]. For this reason using the same
mechanism on ACPI is not possible. A mechanism to refer to non-device ACPI nodes
is documented in [7].
ACPI allows (as does DT) using integer arguments after the reference. A
combination of the LED driver device reference and an integer argument,
referring to the "reg" property of the relevant LED, is used to identify
individual LEDs. The value of the "reg" property is a contract between the
firmware and software, it uniquely identifies the LED driver outputs.
Under the LED driver device, The first hierarchical data extension package list
entry shall contain the string "led@" followed by the number of the LED,
followed by the referred object name. That object shall be named "LED" followed
by the number of the LED.
An ASL example of a camera sensor device and a LED driver device for two LEDs.
Objects not relevant for LEDs or the references to them have been omitted.

* Texas Instruments - lm3532 White LED driver with ambient light sensing
capability.
The LM3532 provides the 3 high-voltage, low-side current sinks. The device is
programmable over an I2C-compatible interface and has independent
current control for all three channels. The adaptive current regulation
method allows for different LED currents in each current sink thus allowing
for a wide variety of backlight and keypad applications.
The main features of the LM3532 include dual ambient light sensor inputs
each with 32 internal voltage setting resistors, 8-bit logarithmic and linear
brightness control, dual external PWM brightness control inputs, and up to
1000:1 dimming ratio with programmable fade in and fade out settings.
Required properties:
- compatible : "ti,lm3532"
- reg : I2C slave address
- #address-cells : 1
- #size-cells : 0
Optional properties:
- enable-gpios : gpio pin to enable (active high)/disable the device.
- ramp-up-us - The Run time ramp rates/step are from one current
set-point to another after the device has reached its
initial target set point from turn-on
- ramp-down-us - The Run time ramp rates/step are from one current
set-point to another after the device has reached its
initial target set point from turn-on
Range for ramp settings: 8us - 65536us
Optional properties if ALS mode is used:
- ti,als-vmin - Minimum ALS voltage defined in Volts
- ti,als-vmax - Maximum ALS voltage defined in Volts
Per the data sheet the max ALS voltage is 2V and the min is 0V
- ti,als1-imp-sel - ALS1 impedance resistor selection in Ohms
- ti,als2-imp-sel - ALS2 impedance resistor selection in Ohms
Range for impedance select: 37000 Ohms - 1190 Ohms
Values above 37kohms will be set to the "High Impedance" setting
- ti,als-avrg-time-us - Determines the length of time the device needs to
average the two ALS inputs. This is only used if
the input mode is LM3532_ALS_INPUT_AVRG.
Range: 17920us - 2293760us
- ti,als-input-mode - Determines how the device uses the attached ALS
devices.
0x00 - ALS1 and ALS2 input average
0x01 - ALS1 Input
0x02 - ALS2 Input
0x03 - Max of ALS1 and ALS2
Required child properties:
- reg : Indicates control bank the LED string is controlled by
- led-sources : see Documentation/devicetree/bindings/leds/common.txt
- ti,led-mode : Defines if the LED strings are manually controlled or
if the LED strings are controlled by the ALS.
0x00 - LED strings are I2C controlled via full scale
brightness control register
0x01 - LED strings are ALS controlled
Optional LED child properties:
- label : see Documentation/devicetree/bindings/leds/common.txt
- linux,default-trigger :
see Documentation/devicetree/bindings/leds/common.txt
