attempt to commonize how chargers and their supplies are linked.
Following common dt convention, the "supplied-to" char** list is
replaced with phandle lists defined in the supplies which contain
phandles of their suppliers.
This has the effect however of introducing an inversion in the internal
mechanics of how this information is stored. In the case of non-dt,
the char** list of supplies is stored in the charger. In the dt case,
a device_node * list is stored in the supplies of their chargers,
however this seems to be the only way to support this.
hits, although I didn't look at the complexity of most of them. Would it
be possible to invert all the current in-kernel uses to represent a
supplied_from/by model instead? That would mean the proposed DT binding
would then represent the same relationship ordering as the kernel code,
which would be easier to handle.
