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:
It was compiled together with the most recent Tianocore EDK2 revision.
Please refer to the firmware build instruction on MacchiatoBin board:
ACPI representation of PP2 controllers (withouth PHY support) can
be viewed in the github:
* Armada 7040 DB:
I will appreciate any comments or remarks.
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.
