drivers: mdio: add stm32 mdio support
MDIO is part of the ETH IP, but some phy chip may need a specific phy driver to set up certain vendor registers enabling particular features. Add support for stm32 mdio access. Signed-off-by: Angelo Dureghello <adureghello@baylibre.com>

dts: arm: st: add mdio node for h5 and h7
Add mdio node for h5 and h7 series. Since MDIO registers are part of the same ETH hw IP, keeping mdio node just as a child of mac/eth, cannot see as appropriate to assign an adddress to it. Signed-off-by: Angelo Dureghello <adureghello@baylibre.com>
-
boards: st: add mdio and phy nodes
Add mdio and phy nodes for h5/h7 families. Signed-off-by: Angelo Dureghello <adureghello@baylibre.com>

soc: st: set soc-level phy priority
Introducing MDIO and PHY support for stm32, phy driver gets error (-116) if it tries to read phy chip id, since MDIO IP is part of ETH IP, and eth hw module is still not initialized. Forcing a priority that allows possibly connected PHY chip to be detected properly at initial boot. Signed-off-by: Angelo Dureghello <adureghello@baylibre.com>

drivers: eth: eth_stm32: use phy api support for h5/h7
Use PHY apis to access the PHY, to avoid any kind of collisions with other tasks using the PHY apis. Signed-off-by: Angelo Dureghello <adureghello@baylibre.com>

drivers: eth: phy: adin2111: add support for adin1100 phy
Add support for similar adin1100 phy, boath are 10Base-T1L, only difference is that adin1100 connects through r/mii. Signed-off-by: Angelo Dureghello <angelo@kernel-space.org>
