| * Socionext AVE ethernet controller |
| |
| This describes the devicetree bindings for AVE ethernet controller |
| implemented on Socionext UniPhier SoCs. |
| |
| Required properties: |
| - compatible: Should be |
| - "socionext,uniphier-pro4-ave4" : for Pro4 SoC |
| - "socionext,uniphier-pxs2-ave4" : for PXs2 SoC |
| - "socionext,uniphier-ld11-ave4" : for LD11 SoC |
| - "socionext,uniphier-ld20-ave4" : for LD20 SoC |
| - "socionext,uniphier-pxs3-ave4" : for PXs3 SoC |
| - reg: Address where registers are mapped and size of region. |
| - interrupts: Should contain the MAC interrupt. |
| - phy-mode: See ethernet.txt in the same directory. Allow to choose |
| "rgmii", "rmii", "mii", or "internal" according to the PHY. |
| The acceptable mode is SoC-dependent. |
| - phy-handle: Should point to the external phy device. |
| See ethernet.txt file in the same directory. |
| - clocks: A phandle to the clock for the MAC. |
| For Pro4 SoC, that is "socionext,uniphier-pro4-ave4", |
| another MAC clock, GIO bus clock and PHY clock are also required. |
| - clock-names: Should contain |
| - "ether", "ether-gb", "gio", "ether-phy" for Pro4 SoC |
| - "ether" for others |
| - resets: A phandle to the reset control for the MAC. For Pro4 SoC, |
| GIO bus reset is also required. |
| - reset-names: Should contain |
| - "ether", "gio" for Pro4 SoC |
| - "ether" for others |
| - socionext,syscon-phy-mode: A phandle to syscon with one argument |
| that configures phy mode. The argument is the ID of MAC instance. |
| |
| Optional properties: |
| - local-mac-address: See ethernet.txt in the same directory. |
| |
| Required subnode: |
| - mdio: A container for child nodes representing phy nodes. |
| See phy.txt in the same directory. |
| |
| Example: |
| |
| ether: ethernet@65000000 { |
| compatible = "socionext,uniphier-ld20-ave4"; |
| reg = <0x65000000 0x8500>; |
| interrupts = <0 66 4>; |
| phy-mode = "rgmii"; |
| phy-handle = <ðphy>; |
| clock-names = "ether"; |
| clocks = <&sys_clk 6>; |
| reset-names = "ether"; |
| resets = <&sys_rst 6>; |
| socionext,syscon-phy-mode = <&soc_glue 0>; |
| local-mac-address = [00 00 00 00 00 00]; |
| |
| mdio { |
| #address-cells = <1>; |
| #size-cells = <0>; |
| |
| ethphy: ethphy@1 { |
| reg = <1>; |
| }; |
| }; |
