The current implementation configures RGMII using device tree phy-mode property and then calls genphy_config adin_config_rgmii_mode is derived from: https://github.com/varigit/linux-imx/blob/lf-5.10.y_var04/drivers/net/phy/adin.c#L218-L262 Signed-off-by: Nate Drude <nate.d@variscite.com> Reviewed-by: Ramon Fried <rfried.dev@gmail.com>

* Analog Devices ADIN PHY Device Tree binding
|
|
|
|
Required properties:
|
|
- reg: PHY address
|
|
|
|
Optional properties:
|
|
- adi,rx-internal-delay-ps: RGMII RX Clock Delay used only when PHY operates
|
|
in RGMII mode with internal delay (phy-mode is 'rgmii-id' or
|
|
'rgmii-rxid') in pico-seconds.
|
|
- adi,tx-internal-delay-ps: RGMII TX Clock Delay used only when PHY operates
|
|
in RGMII mode with internal delay (phy-mode is 'rgmii-id' or
|
|
'rgmii-txid') in pico-seconds.
|
|
- adi,phy-mode-override: Override phy-mode property for adin. This is useful
|
|
when a single device tree supports an adin PHY (e.g. ADIN1300)
|
|
or another PHY (e.g. AR8033) at the same address, but they require
|
|
different phy-modes.
|
|
|
|
Example:
|
|
|
|
ethernet-phy@0 {
|
|
reg = <0>;
|
|
|
|
adi,rx-internal-delay-ps = <1800>;
|
|
adi,tx-internal-delay-ps = <2200>;
|
|
adi,phy-mode-override = "rgmii-id";
|
|
};
