Hi, This is a third version of the patchset introducing mvpp2 driver ability to operate with ACPI. Until follow-up generic MDIO is introduced it can using the link interrupt capability (a.k.a. in-band management) on all ports, 1000BaseT RGMII included. Driver operation was tested on top of the net-next branch with both DT and ACPI on MacchiatoBin and Armada 7040 DB boards.
The main changes were requested during v2 review, which was adding generic helper routines for: * interating over available fwnodes (new patch 4/7) * getting IRQ directly from fwnode (new patch 3/7) Thanks to the latter the driver code could be simplified and allowed to drop formula-based IRQ obtaining. Changes are summarized in the changelog below. mvpp2 driver can work with the ACPI representation, as exposed on a public branch: https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/commits/marvell-armada-wip It was compiled together with the most recent Tianocore EDK2 revision. Please refer to the firmware build instruction on MacchiatoBin board: http://wiki.macchiatobin.net/tiki-index.php?page=Build+from+source+-+UEFI+EDK+II ACPI representation of PP2 controllers (withouth PHY support) can be viewed in the github: * MacchiatoBin: https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/blob/71ae395da1661374b0f07d1602afb1eee56e9794/Platforms/Marvell/Armada/AcpiTables/Armada80x0McBin/Dsdt.asl#L201 * Armada 7040 DB: https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/blob/71ae395da1661374b0f07d1602afb1eee56e9794/Platforms/Marvell/Armada/AcpiTables/Armada70x0/Dsdt.asl#L131 I will appreciate any comments or remarks. Best regards, Marcin Changelog: v2 -> v3: * 1/7, 2/7 - Add Rafael's Acked-by's * 3/7, 4/7 - New patches * 6/7, 7/7 - Update driver with new helper routines usage - Improve commit log. v1 -> v2: * Remove MDIO patches * Use PP2 ports only with link interrupts * Release second region resources in mvpp2 driver (code moved from mvmdio), as explained in details in 5/5 commit message.
