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: --- 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 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 (5): Documentation: ACPI: DSD: Document MDIO PHY net/fsl: store mdiobus fwnode net: phy: introduce phy_find_by_fwnode() 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 | 2 + drivers/net/phy/mdio_bus.c | 25 ++++++ drivers/net/phy/phy_device.c | 21 +++++ drivers/net/phy/phylink.c | 33 +++++++ include/linux/phy.h | 2 + include/linux/phylink.h | 3 + 8 files changed, 216 insertions(+), 30 deletions(-) create mode 100644 Documentation/firmware-guide/acpi/dsd/phy.rst -- 2.17.1
