| 2 | ------------------------------ |
| 3 | |
| 4 | This comphy controller can be found on Marvell Armada 38x. It provides a |
| 5 | number of shared PHYs used by various interfaces (network, sata, usb, |
| 6 | PCIe...). |
| 7 | |
| 8 | Required properties: |
| 9 | |
| 10 | - compatible: should be "marvell,armada-380-comphy" |
| 11 | - reg: should contain the comphy register location and length. |
| 12 | - #address-cells: should be 1. |
| 13 | - #size-cells: should be 0. |
| 14 | |
| 15 | Optional properties: |
| 16 | |
| 17 | - reg-names: must be "comphy" as the first name, and "conf". |
| 18 | - reg: must contain the comphy register location and length as the first |
| 19 | pair, followed by an optional configuration register address and |
| 20 | length pair. |
| 21 | |
| 22 | A sub-node is required for each comphy lane provided by the comphy. |
| 23 | |
| 24 | Required properties (child nodes): |
| 25 | |
| 26 | - reg: comphy lane number. |
| 27 | - #phy-cells : from the generic phy bindings, must be 1. Defines the |
| 28 | input port to use for a given comphy lane. |
| 29 | |
| 30 | Example: |
| 31 | |
| 32 | comphy: phy@18300 { |
| 33 | compatible = "marvell,armada-380-comphy"; |
| 34 | reg-names = "comphy", "conf"; |
| 35 | reg = <0x18300 0x100>, <0x18460 4>; |
| 36 | #address-cells = <1>; |
| 37 | #size-cells = <0>; |
| 38 | |
| 39 | cpm_comphy0: phy@0 { |
| 40 | reg = <0>; |
| 41 | #phy-cells = <1>; |
| 42 | }; |
| 43 | |
| 44 | cpm_comphy1: phy@1 { |
| 45 | reg = <1>; |
| 46 | #phy-cells = <1>; |
| 47 | }; |
| 48 | }; |
