[PATCH v3 0/3] add ast2400/2500 phy-handle support

From: Ivan Mikhaylov
Date: Fri Oct 30 2020 - 09:32:52 EST


This patch introduces ast2400/2500 phy-handle support with an embedded
MDIO controller. At the current moment it is not possible to set options
with this format on ast2400/2500:

mac {
phy-handle = <&phy>;
phy-mode = "rgmii";

mdio {
#address-cells = <1>;
#size-cells = <0>;

phy: ethernet-phy@0 {
compatible = "ethernet-phy-idxxxx.yyyy";
reg = <0>;
};
};
};

The patch fixes it and gets possible PHYs and register them with
of_mdiobus_register.

Changes from v3:
1. add dt-bindings description of MDIO node and phy-handle option
with example.

Changes from v2:
1. change manual phy interface type check on phy_interface_mode_is_rgmii
function.
2. add err_phy_connect label.
3. split ftgmac100_destroy_mdio into ftgmac100_phy_disconnect and
ftgmac100_destroy_mdio.
4. remove unneeded mdio_np checks.

Changes from v1:
1. split one patch into two.
