* Soltech JSA-1127 ambient light sensor
|
||
|
|
|
||
|
|
nvs_ drivers use the NVidia Sensor (NVS) framework.
|
||
|
|
See the nvs.txt documentation for NVS DT capabilities.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: must be "solteamopto,jsa1127"
|
||
|
|
- reg: i2c address of the device. It can be 0x29, 0x39 or 0x44.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- status: set to "ok" or "okay" for normal operation. Set to anything else
|
||
|
|
to unload the driver without ever communicating with the device.
|
||
|
|
Note: The "anything else" above is typically "disabled".
|
||
|
|
Since the driver will unload without communicating with the device, the
|
||
|
|
device will be left in its POR state.
|
||
|
|
- light_disable: Setting this property to <1> will disable the device and
|
||
|
|
unload the driver.
|
||
|
|
- vdd-supply: regulator supply for the chip
|
||
|
|
Note: This is required if the driver is to control the regulator.
|
||
|
|
Format: light_mode_settingname
|
||
|
|
Where: 'light' refers to the light sensor classification
|
||
|
|
'mode' refers to data collection mode:
|
||
|
|
hwm = hardware mode
|
||
|
|
swm = software mode
|
||
|
|
hyb = hybrid mode
|
||
|
|
'settingname' is a named identifier and rather free-form, can include more underscores if desired
|
||
|
|
|
||
|
