Hello 2 sunxi board still does not have ethernet working, orangepi 1+ and orangepi 3. This is due to the fact thoses boards have a PHY which need 2 regulators. A first attempt by Ondřej Jirman was made to support them was made by adding support in stmmac driver: https://lore.kernel.org/lkml/20190820145343.29108-6-megous@xxxxxxxxxx/ Proposal rejected, since regulators need to be handled by the PHY core. My first tentative was to just add handling of phy and phy-io in phy-core: https://lore.kernel.org/netdev/20220509074857.195302-7-clabbe@xxxxxxxxxxxx/T/ But having hard-coded phy names was rejected. Second tentative tryed the same path than clocks and clock-names for regulators. https://lore.kernel.org/netdev/0518eef1-75a6-fbfe-96d8-bb1fc4e5178a@xxxxxxxxxx/t/ But using this was rejected by DT maintainers. So v3 use a new regulator_bulk_get_all() which grab all supplies properties in a DT node. But this way could have some problem, a netdev driver could handle already its PHY (like dwmac-sun8i already do) and so both phy-core and the netdev will use both. It is why phy-supply was renamed in ephy-supply in patch #3. This serie was tested on whole range of board and PHY architecture: - internal PHY * sun8i-h3-orangepi-pc - external PHY * sun50i-h6-pine-h64 * sun8i-r40-bananapi-m2-ultra * sun8i-a83t-bananapi-m3 * sun50i-a64-bananapi-m64 * sun50i-h6-orangepi-3 * sun50i-h5-nanopi-neo-plus2 The resume/suspend of PHY was tested. Regards changes since v1: - Add regulator_bulk_get_all for ease handling of PHY regulators - Removed all convertion patchs to keep DT compatibility. Changes since v2: - removed use of regulator-names and regulators list. Changes since v3: - fixes kbuild robot report Corentin Labbe (2): regulator: Add of_regulator_bulk_get_all phy: handle optional regulator for PHY Ondřej Jirman (1): arm64: dts: allwinner: orange-pi-3: Enable ethernet .../dts/allwinner/sun50i-h6-orangepi-3.dts | 38 ++++++++ drivers/net/mdio/fwnode_mdio.c | 31 ++++++- drivers/net/phy/phy_device.c | 10 ++ drivers/regulator/of_regulator.c | 92 +++++++++++++++++++ include/linux/phy.h | 3 + include/linux/regulator/consumer.h | 8 ++ 6 files changed, 181 insertions(+), 1 deletion(-) -- 2.37.4
