Unfortunately changing that details requires pretty much the entire series to be rewritten (sorry!). I won't do any detailed review on patches 2-6 until I see the next version. g. > > --- a/drivers/bus/fsl-mc/fsl-mc-bus.c > +++ b/drivers/bus/fsl-mc/fsl-mc-bus.c > @@ -931,6 +931,7 @@ static int fsl_mc_bus_probe(struct platform_device *pdev) > if (error < 0) > goto error_cleanup_mc_io; > > + mc_bus_dev->dev.fwnode = pdev->dev.fwnode; > mc->root_mc_bus_dev = mc_bus_dev; > return 0; > > > Changes in v7: > - remove unnecessary -ve check for u32 var > - 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() > > Calvin Johnson (6): > Documentation: ACPI: DSD: Document MDIO PHY > net: phy: introduce device_mdiobus_register() > net/fsl: use device_mdiobus_register() > net: phy: introduce phy_find_by_mdio_handle() > phylink: introduce phylink_fwnode_phy_connect() > net: dpaa2-mac: Add ACPI support for DPAA2 MAC driver > > Documentation/firmware-guide/acpi/dsd/phy.rst | 90 +++++++++++++++++++ > .../net/ethernet/freescale/dpaa2/dpaa2-mac.c | 70 ++++++++------- > drivers/net/ethernet/freescale/xgmac_mdio.c | 3 +- > drivers/net/phy/mdio_bus.c | 51 +++++++++++ > drivers/net/phy/phy_device.c | 40 +++++++++ > drivers/net/phy/phylink.c | 32 +++++++ > include/linux/mdio.h | 1 + > include/linux/phy.h | 2 + > include/linux/phylink.h | 3 + > 9 files changed, 260 insertions(+), 32 deletions(-) > create mode 100644 Documentation/firmware-guide/acpi/dsd/phy.rst >

I'll rework on the patches and send a new series. Thanks Calvin
