Marcin Wojtas | 3f51850 | 2014-07-10 16:52:13 -0300 | [diff] [blame] | 1 | * Marvell Armada 375 Ethernet Controller (PPv2) |
| 2 | |
| 3 | Required properties: |
| 4 | |
| 5 | - compatible: should be "marvell,armada-375-pp2" |
| 6 | - reg: addresses and length of the register sets for the device. |
| 7 | Must contain the following register sets: |
| 8 | - common controller registers |
| 9 | - LMS registers |
| 10 | In addition, at least one port register set is required. |
| 11 | - clocks: a pointer to the reference clocks for this device, consequently: |
| 12 | - main controller clock |
| 13 | - GOP clock |
| 14 | - clock-names: names of used clocks, must be "pp_clk" and "gop_clk". |
| 15 | |
| 16 | The ethernet ports are represented by subnodes. At least one port is |
| 17 | required. |
| 18 | |
| 19 | Required properties (port): |
| 20 | |
| 21 | - interrupts: interrupt for the port |
| 22 | - port-id: should be '0' or '1' for ethernet ports, and '2' for the |
| 23 | loopback port |
| 24 | - phy-mode: See ethernet.txt file in the same directory |
| 25 | |
| 26 | Optional properties (port): |
| 27 | |
| 28 | - marvell,loopback: port is loopback mode |
| 29 | - phy: a phandle to a phy node defining the PHY address (as the reg |
| 30 | property, a single integer). Note: if this property isn't present, |
| 31 | then fixed link is assumed, and the 'fixed-link' property is |
| 32 | mandatory. |
| 33 | |
| 34 | Example: |
| 35 | |
| 36 | ethernet@f0000 { |
| 37 | compatible = "marvell,armada-375-pp2"; |
| 38 | reg = <0xf0000 0xa000>, |
| 39 | <0xc0000 0x3060>, |
| 40 | <0xc4000 0x100>, |
| 41 | <0xc5000 0x100>; |
| 42 | clocks = <&gateclk 3>, <&gateclk 19>; |
| 43 | clock-names = "pp_clk", "gop_clk"; |
| 44 | status = "okay"; |
| 45 | |
| 46 | eth0: eth0@c4000 { |
| 47 | interrupts = <GIC_SPI 37 IRQ_TYPE_LEVEL_HIGH>; |
| 48 | port-id = <0>; |
| 49 | status = "okay"; |
| 50 | phy = <&phy0>; |
| 51 | phy-mode = "gmii"; |
| 52 | }; |
| 53 | |
| 54 | eth1: eth1@c5000 { |
| 55 | interrupts = <GIC_SPI 41 IRQ_TYPE_LEVEL_HIGH>; |
| 56 | port-id = <1>; |
| 57 | status = "okay"; |
| 58 | phy = <&phy3>; |
| 59 | phy-mode = "gmii"; |
| 60 | }; |
| 61 | }; |
