Why do you need a child node for this? Is there more than 1 instance in
a PMIC? Every sub-function of a PMIC doesn't have to have a DT node.
We currently have another downstream driver (which is planned to get upstreamed)
which also needs a handle to a pbs device in order to properly trigger events.
Does it have to be a separate driver? Or is it a part of the LPG driver, just being artificially split away?
Sure, I just discussed with team and we are ok with removing this as a separate driver. Will have that
for next version.
I saw that the PBS can also be used with the haptics device. Will it
talk to the LPG driver?
