Properties

Properties not inherited from the base binding file.

Name

Type

Details

pinctrl-0

phandles

 
Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.

This property is required.

pinctrl-names

string-array

 
Names for the provided states. The number of names needs to match the
number of states.

This property is required.

enable-pin

int

 
The enable pin to use, to enable a connected QDEC device

For pins P0.0 through P0.31, use the pin number. For example,
to use P0.16 for the A pin, set:

    enable-pin = <16>;

For pins P1.0 through P1.31, add 32 to the pin number. For
example, to use P1.2 for the A pin, set:

    enable-pin = <34>;  /* 32 + 2 */

led-pre

int

 
Time LED is enabled prior to sampling event (in us)

This property is required.

steps

int

 
Number of steps on the rotating wheel

This property is required.

friendly-name

string

 
Human readable string describing the sensor. It can be used to
distinguish multiple instances of the same model (e.g., lid accelerometer
vs. base accelerometer in a laptop) to a host operating system.

This property is defined in the Generic Sensor Property Usages of the HID
Usage Tables specification
(https://usb.org/sites/default/files/hut1_3_0.pdf, section 22.5).
