Subject: [net-next PATCH v4 0/6]  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;
        return 0;


Changes in v4:
- release fwnode_mdio after use
- return ERR_PTR instead of NULL
- introduce device_mdiobus_register()

Changes in v3:
- cleanup based on v2 comments
- Added description for more properties
- Added MDIO node DSDT entry
- introduce fwnode_mdio_find_bus()
- renamed and improved phy_find_by_fwnode()
- cleanup based on v2 comments
- move code into phylink_fwnode_phy_connect()

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