| TI SoC Davinci/Keystone2 MDIO Controller Device Tree Bindings |
| --------------------------------------------------- |
| |
| Required properties: |
| - compatible : Should be "ti,davinci_mdio" |
| and "ti,keystone_mdio" for Keystone 2 SoCs |
| and "ti,cpsw-mdio" for am335x, am472x, am57xx/dra7, dm814x SoCs |
| and "ti,am4372-mdio" for am472x SoC |
| - 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>; |
| }; |
