Subject: [net-next PATCH v7 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.
Patch "net: dpaa2-mac: Add ACPI support for DPAA2 MAC driver" depends on
https://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/linux.git/commit/?h=acpi/for-next&id=c279c4cf5bcd3c55b4fb9709d9036cd1bfe3beb8
Remaining patches are independent of the above patch and can be applied without
any issues.
Device Tree can be tested on LX2160A-RDB with the below change which is also
available in the above referenced patches:

- assign flags to phy_dev
Changes in v6:
- change device_mdiobus_register() parameter position
- improve documentation
- change device_mdiobus_register() parameter position
- clean up phylink_fwnode_phy_connect()
Changes in v5:
- add description
- clean up if else
- rename phy_find_by_fwnode() to phy_find_by_mdio_handle()
- add docment for phy_find_by_mdio_handle()
- error out DT in phy_find_by_mdio_handle()
- clean up err return
- return -EINVAL for invalid fwnode
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()
