(for seeing what's new)\nBut the final serie could have some patch squashed if someone want.\nLike squashing patch and 1 and 2 (documentation)\n\nThe first 7 patch should go via the sunxi tree, the last three via the net tree.\n\nRegards\n\nChanges since v8:\n- added reference to mdio-mux.txt in documentation\n- removed compatible mdio-mux\n- added mdio-parent-bus\n\nChanges since v7:\n- moved mdio-mux ouf of mdio as asked by Andrew Lunn\n- reordered patchs order\n\nChanges since v6:\n- renamed external mdio to \"external_mdio\"\n- added compatible to mdio-mux and internal-mdio\n- removed usage of phy-is-integrated\n- renamed do_not_scan to compatible_muxes (patch 10)\n- patch 8 9 of v6 are squashed\n\nChanges since v5:\n- reordered patch 1 and 2\n- mdio-mux node is now a mdio's child\n- added patch 11 for removing unnecessary scan of mdio-mux\n\nChanges since v4:\n- Update documentation for new bindings\n- Added 4 patchs for bring back reverted stuff of 4.13\n- dwmac-sun8i now handle mdio-mux\n- MDIO use now compatible = \"snps,dwmac-mdio\";\n\nChanges since v3:\n- Added a patch for handling fixed-link\n- Updated documentation\n\nChanges since v2:\n- Add a MDIO mux for creating distinction between integrated and external MDIO.\n- phy-is-integrated is not set in dtsi.\n\nChanges since v1:\n- Dropped phy-is-integrated documentation patch since another same patch was already merged\n- Moved phy-is-integrated from SoC dtsi to final board DT.\n\nAcked-by: Florian Fainelli \n\nCorentin Labbe (10):\n dt-bindings: net: Restore sun8i dwmac binding\n dt-bindings: net: dwmac-sun8i: update documentation about integrated\n PHY\n arm: dts: sunxi: h3/h5: Restore EMAC changes\n arm: dts: sunxi: h3/h5: represent the mdio switch used by\n sun8i-h3-emac\n arm: dts: sunxi: Restore EMAC changes (boards)\n arm64: dts: allwinner: Restore EMAC changes\n arm64: dts: allwinner: add snps,dwmac-mdio compatible to emac/mdio\n net: stmmac: snps,dwmac-mdio MDIOs are automatically registered\n net: stmmac: dwmac-sun8i: Handle integrated/external MDIOs\n net: stmmac: sun8i: Restore the compatibles\n\n .../devicetree/bindings/net/dwmac-sun8i.txt | 205 ++++++++++++\n arch/arm/boot/dts/sun8i-h2-plus-orangepi-zero.dts | 9 +\n arch/arm/boot/dts/sun8i-h3-bananapi-m2-plus.dts | 19 ++\n arch/arm/boot/dts/sun8i-h3-nanopi-m1-plus.dts | 19 ++\n arch/arm/boot/dts/sun8i-h3-nanopi-neo.dts | 7 +\n arch/arm/boot/dts/sun8i-h3-orangepi-2.dts | 8 +\n arch/arm/boot/dts/sun8i-h3-orangepi-one.dts | 8 +\n arch/arm/boot/dts/sun8i-h3-orangepi-pc-plus.dts | 5 +\n arch/arm/boot/dts/sun8i-h3-orangepi-pc.dts | 8 +\n arch/arm/boot/dts/sun8i-h3-orangepi-plus.dts | 22 ++\n arch/arm/boot/dts/sun8i-h3-orangepi-plus2e.dts | 16 +\n arch/arm/boot/dts/sunxi-h3-h5.dtsi | 48 +++\n .../boot/dts/allwinner/sun50i-a64-bananapi-m64.dts | 16 +\n .../boot/dts/allwinner/sun50i-a64-pine64-plus.dts | 15 +\n .../arm64/boot/dts/allwinner/sun50i-a64-pine64.dts | 17 +\n .../dts/allwinner/sun50i-a64-sopine-baseboard.dts | 16 +\n arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi | 21 ++\n .../boot/dts/allwinner/sun50i-h5-nanopi-neo2.dts | 17 +\n .../boot/dts/allwinner/sun50i-h5-orangepi-pc2.dts | 17 +\n .../dts/allwinner/sun50i-h5-orangepi-prime.dts | 17 +\n drivers/net/ethernet/stmicro/stmmac/Kconfig | 1 +\n drivers/net/ethernet/stmicro/stmmac/dwmac-sun8i.c | 361 +++++++++++++--------\n .../net/ethernet/stmicro/stmmac/stmmac_platform.c | 4 -\n 23 files changed, 742 insertions(+), 134 deletions(-)\n create mode 100644 Documentation/devicetree/bindings/net/dwmac-sun8i.txt"}
