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

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()
