The similar MDIO HW blocks is used by keystone 2 SoCs as in Davinci SoCs: - one in Gigabit Ethernet (GbE) Switch Subsystem See http://www.ti.com/lit/ug/sprugv9d/sprugv9d.pdf - one in 10 Gigabit Ethernet Subsystem See http://www.ti.com/lit/ug/spruhj5/spruhj5.pdf Hence, reuse Davinci MDIO driver for Keystone 2 and enable TI networking for Keystone 2 devices Reviewed-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Acked-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Reviewed-by: Lad, Prabhakar <prabhakar.csengg@gmail.com> Signed-off-by: David S.

TI SoC Davinci/Keystone2 MDIO Controller Device Tree Bindings
|
|
---------------------------------------------------
|
|
|
|
Required properties:
|
|
- compatible : Should be "ti,davinci_mdio" or "ti,keystone_mdio"
|
|
- reg : physical base address and size of the davinci mdio
|
|
registers map
|
|
- bus_freq : Mdio Bus frequency
|
|
|
|
Optional properties:
|
|
- ti,hwmods : Must be "davinci_mdio"
|
|
|
|
Note: "ti,hwmods" field is used to fetch the base address and irq
|
|
resources from TI, omap hwmod data base during device registration.
|
|
Future plan is to migrate hwmod data base contents into device tree
|
|
blob so that, all the required data will be used from device tree dts
|
|
file.
|
|
|
|
Examples:
|
|
|
|
mdio: davinci_mdio@4A101000 {
|
|
compatible = "ti,davinci_mdio";
|
|
reg = <0x4A101000 0x1000>;
|
|
bus_freq = <1000000>;
|
|
};
|
|
|
|
(or)
|
|
|
|
mdio: davinci_mdio@4A101000 {
|
|
compatible = "ti,davinci_mdio";
|
|
ti,hwmods = "davinci_mdio";
|
|
bus_freq = <1000000>;
|
|
};
