- ramp-down-us: Current ramping from one brightness level to
the a lower brightness level.
Range from 2048 us - 117.44 s
+ - ti,brightness-resolution - This determines whether to use 8 bit brightness
+ mode or 11 bit brightness mode. If this value is
+ not set the device is defaulted to the preferred
+ 8bit brightness mode per 7.3.4.1 of the data
+ sheet. This setting can either be in the parent
+ node or as part of the LED child nodes. This
+ is determined by the part itself if the strings
+ have a common brightness register or individual
+ brightness registers.
+ The values are 255 (8bit) or 2047 (11bit).
Required node:
- backlight: All LMU devices have backlight child nodes.
