Hi, I'm not splitting this series in two after all. After thinking about this for some time, I decided to add support for static software nodes. I did not want to support them because I don't want to make it easy to maintain board files, but in end they make the use of the software nodes so much more easier compared to if we always had to dynamically allocate them that it's a no-brainer. The references can now be also described statically. Actually, those can now only be described statically. Hans! I applied (hopefully) all of the fixes you proposed in v3. I hope you have time to test these. Here's the cover letter from v3: This is the third version of my proposal to add reference handling to the software node code. In this version I renamed ACPI_NAME_SIZE to ACPI_NAMESEG_SIZE in 6/13, and slit patch 9/13 in two separate patches (9/13 and 10/13) as suggested by Andy. Patch 9/13 will now only move the registration of max17047 out of probe, and 10/13 will introduce the software nodes. v2 cover letter: This is the second version of this series. In this version I'm introducing a new helper device_find_child_by_name() as proposed by Andy. Andy requested also another helper that could be used for chaining the fwnodes, but I decided not to add that now. I would like to still think about how we should handle exceptions like if there already is a secondary node assigned for a node. v1 cover letter: This series adds support for software fwnode reference handling. In practice it means making fwnode_property_get_reference_args() function usable in the drivers also with software nodes. I send the series originally as RFC [1]. As the first user for the software node references, I'm converting intel_cht_int33fe.c to use them as part of the series.
