I have the same (limited by experience) opinion. Working sort of
near som audio drivers I have understood that power sequencing
is a big issue not only for things like this backlight example, but
even more so in the area of audio to avoid clicks and pops.

Is it correct to assume that this library will be useful also for ALSA
SoC type of devices?

Then whether to couple that to DT or ACPI or SFI or whatever
is a different discussion altogether.
