This is continuation of the work done by Corentin: https://lore.kernel.org/linux-sunxi/20221115073603.3425396-1-clabbe@xxxxxxxxxxxx/ In short, Orange Pi 3 and Orange Pi One Plus boards have ethernet PHYs which are powered by two voltage regulators. They have to be powered on in correct order or otherwise they are not functional. Please see link above for previous discussion on how to achieve that. Best regards, Jernej changes since v1: - Add regulator_bulk_get_all for ease handling of PHY regulators - Removed all conversion patches to keep DT compatibility. Changes since v2: - removed use of regulator-names and regulators list. Changes since v3: - fixes kbuild robot report Changes since v4: - dropped merged patches - reworked PHY powering on/off patch - added Orange Pi One Plus patch, since it has same issue Corentin Labbe (1): phy: handle optional regulator for PHY Jernej Skrabec (1): arm64: dts: allwinner: orange-pi-one-plus: Fix ethernet Ondrej Jirman (1): arm64: dts: allwinner: orange-pi-3: Enable ethernet .../dts/allwinner/sun50i-h6-orangepi-3.dts | 40 ++++++++++++++ .../allwinner/sun50i-h6-orangepi-one-plus.dts | 29 +++++++--- drivers/net/mdio/fwnode_mdio.c | 53 ++++++++++++++++++- drivers/net/phy/phy_device.c | 6 +++ include/linux/phy.h | 3 ++ 5 files changed, 122 insertions(+), 9 deletions(-) -- 2.43.0
