[net-next: PATCH v2 0/5] Armada 7k/8k PP2 ACPI support

From: Marcin Wojtas
Date: Sun Dec 31 2017 - 07:00:19 EST


This a second version of a patchset, which introduces ACPI support
in mvpp2 driver. Comparing to the initial one, all patches
touching generic ACPI MDIO bus / PHY handling were removed
and after some modifications will be resend separately. They
may require a longer discussion in terms of phylink support
and ACPI specification extensions.

This way mvpp2 driver is able to operate 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.

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:
* MacchiatoBin:

* Armada 7040 DB:

I will appreciate any comments or remarks.

Best regards,

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.
