I have tested all this on GS7 successfully with ip=dhcp on 100M FD. Besides the misplacement of the 'phy-connection-type' as reported by Sergei, this looks good to me: Reviewed-by: Florian Fainelli Thanks! > > Antoine T?nart (1): > ARM: berlin: Add phy-connection-type to BG2Q PHY > > Sebastian Hesselbarth (8): > phy: marvell: Add support for 88E3016 FastEthernet PHY > net: pxa168_eth: Provide phy_interface mode on platform_data > net: pxa168_eth: Prepare proper libphy handling > net: pxa168_eth: Remove HW auto-negotiaion > net: pxa168_eth: Remove in-driver PHY mangling > ARM: berlin: Add BG2 ethernet DT nodes > ARM: berlin: Add BG2CD ethernet DT nodes > ARM: berlin: Enable ethernet on Sony NSZ-GS7 > > arch/arm/boot/dts/berlin2-sony-nsz-gs7.dts | 2 + > arch/arm/boot/dts/berlin2.dtsi | 36 +++++ > arch/arm/boot/dts/berlin2cd.dtsi | 36 +++++ > arch/arm/boot/dts/berlin2q.dtsi | 1 + > arch/arm/mach-mmp/gplugd.c | 2 + > drivers/net/ethernet/marvell/pxa168_eth.c | 248 ++++++++++++----------------- > drivers/net/phy/marvell.c | 46 ++++++ > include/linux/marvell_phy.h | 1 + > include/linux/pxa168_eth.h | 1 + > 9 files changed, 225 insertions(+), 148 deletions(-) > > --- > Cc: "David S.
