Some BCM63268 bootloaders do not enable the internal PHYs by default. This patch series adds a phy driver to set the registers required for the gigabit PHY to work. Currently the PHY can't be detected until the b53 switch is initialized, but this should be solvable through the device tree. I'm currently investigating whether the the PHY needs the whole switch to be set up or just specific clocks, etc. v2 changes: - Remove changes to b53 dsa code and rework fix as a PHY driver - Use a regmap for accessing GPHY control register - Add documentaion for device tree changes v1: https://lore.kernel.org/netdev/20250206043055.177004-1-kylehendrydev@xxxxxxxxx/ Signed-off-by: Kyle Hendry <kylehendrydev@xxxxxxxxx> Kyle Hendry (5): net: phy: bcm63xx: add support for BCM63268 GPHY net: phy: enable bcm63xx on bmips dt-bindings: net: bcm6368-mdio-mux: add gphy-ctrl property dt-bindings: mfd: brcm: add brcm,bcm63268-gphy-ctrl compatible dt-bindings: mfd: brcm: add gphy controller to BCM63268 sysctl .../mfd/brcm,bcm63268-gpio-sysctl.yaml | 13 +++ .../devicetree/bindings/mfd/syscon.yaml | 2 + .../bindings/net/brcm,bcm6368-mdio-mux.yaml | 7 ++ drivers/net/phy/Kconfig | 4 +- drivers/net/phy/bcm63xx.c | 96 +++++++++++++++++++ 5 files changed, 120 insertions(+), 2 deletions(-) -- 2.43.0
