* Rework net/dsa to use fwnode_*/device_* API * Move a couple of missing routines to fwnode_ equivalents The patchset can be logically split to subsets of commits: 'ports' and 'mdio' subnodes naming, as they don't conform ACPI Transition, as the DT and ACPI topolgies are analogous, except for The vast majority of required changes were simple of_* to fwnode_* Responsible for their enumeration based on the standard _ADR fields andĭescription in _DSD objects under 'device properties' UUID. It turned out that without much hassle it is possible to describeĭSA-compliant switches as child devices of the MDIO busses, which are
I thought it would be worth to experiment with DSA, which seemed NIC drivers, MDIO, PHY, and phylink modifications – the latter three merged The key enablements allowing for adding ACPI support for DSA in Linux were It also enables this feature for ARM64 ACPI users. Addition of switch description toĭSDT/SSDT tables would help to solve many similar cases and use unmodified X86_64 SoCs, which are described by ACPI tables - to use DSA, some tricksĪnd workarounds have to be applied. The above constraint is problematic for the embedded devices based e.g. Platform data - a legacy approach used by older systems that compiled the The only alternative is to pass the information about the topology via (of_*) interface, both in the drivers and the common high-level net/dsa API. The DSA code is strictly dependent on the Device Tree and Open Firmware Words about the background and motivation behind those changes: This patchset introduces the support for DSA in ACPI world.
