Applied to driver-core-testing, thanks!

Once the patches passed 0-day testing they will be merged into driver-core-next.

I did drop those two patches for now, because:

  (1) They're basically dead code.

  (2) It seems that FwNode::property_get_reference_args() leaks a struct
      fwnode_handle reference. property_get_reference_args() explicitly says
      that the caller is responsible "for calling fwnode_handle_put() on the
      returned @args->fwnode pointer", which doesn't seem to happen.

Can you please fix the leak and resend those two patches with an additional one
that adds a sample usage of the introduced methods to the platform sample
driver?
