In the latter a clock handling was significantly simplified by a switch to a devm_clk_bulk_get_optional(). Last but not least two additional MAC configuration modes ACPI desctiption were documented ("managed" and "fixed-link") - they can be processed by the existing fwnode_ phylink helpers and comply with the standard _DSD properties and hierarchical data extension. ACPI Maintainers are therefore added to reviewers' list. More details can be found in the patches and their commit messages. As before, the feature was verified with ACPI on MacchiatoBin, CN913x-DB and Armada 8040 DB (fixed-link handling). Moreover regression tests were performed (old firmware with updated kernel, new firmware with old kernel and the operation with DT). The firmware ACPI description is exposed in the public github branch: https://github.com/semihalf-wojtas-marcin/edk2-platforms/commits/acpi-mdio-r20210613 There is also MacchiatoBin firmware binary available for testing: https://drive.google.com/file/d/1eigP_aeM4wYQpEaLAlQzs3IN_w1-kQr0 I'm looking forward to the comments or remarks.
