| 2 | |
| 3 | Required properties: |
| 4 | - compatible: should contain one of the following version strings: |
| 5 | * "hisilicon,hisi-femac-v1" |
| 6 | * "hisilicon,hisi-femac-v2" |
| 7 | and the soc string "hisilicon,hi3516cv300-femac". |
| 8 | - reg: specifies base physical address(s) and size of the device registers. |
| 9 | The first region is the MAC core register base and size. |
| 10 | The second region is the global MAC control register. |
| 11 | - interrupts: should contain the MAC interrupt. |
| 12 | - clocks: A phandle to the MAC main clock. |
| 13 | - resets: should contain the phandle to the MAC reset signal(required) and |
| 14 | the PHY reset signal(optional). |
| 15 | - reset-names: should contain the reset signal name "mac"(required) |
| 16 | and "phy"(optional). |
| 17 | - phy-mode: see ethernet.txt [1]. |
| 18 | - phy-handle: see ethernet.txt [1]. |
| 19 | - hisilicon,phy-reset-delays-us: triplet of delays if PHY reset signal given. |
| 20 | The 1st cell is reset pre-delay in micro seconds. |
| 21 | The 2nd cell is reset pulse in micro seconds. |
| 22 | The 3rd cell is reset post-delay in micro seconds. |
| 23 | |
| 24 | The MAC address will be determined using the optional properties |
| 25 | defined in ethernet.txt[1]. |
