Subject: [net-next PATCH v2 0/3]  ACPI support for dpaa2 MAC driver.

 This patch series provides ACPI support for dpaa2 MAC driver.
 This also introduces ACPI mechanism to get PHYs registered on a
 MDIO bus and provide them to be connected to MAC.

 This patchset is dependent on the review patches available on:
https://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/linux.git/log/?h=for-review/acpi-iort-id-rework

 Device Tree can be tested with the below change which is also available in
the above referenced review patches:

        mc->root_mc_bus_dev = mc_bus_dev;

Changes in v2:
    - clean up dpaa2_mac_get_node()
    - introduce find_phy_device()
    - use acpi_find_child_device()
