Hisilicon Fast Ethernet MAC controller |
|
|
|
Required properties: |
|
- compatible: should contain one of the following version strings: |
|
* "hisilicon,hisi-femac-v1" |
|
* "hisilicon,hisi-femac-v2" |
|
and the soc string "hisilicon,hi3516cv300-femac". |
|
- reg: specifies base physical address(s) and size of the device registers. |
|
The first region is the MAC core register base and size. |
|
The second region is the global MAC control register. |
|
- interrupts: should contain the MAC interrupt. |
|
- clocks: A phandle to the MAC main clock. |
|
- resets: should contain the phandle to the MAC reset signal(required) and |
|
the PHY reset signal(optional). |
|
- reset-names: should contain the reset signal name "mac"(required) |
|
and "phy"(optional). |
|
- phy-mode: see ethernet.txt [1]. |
|
- phy-handle: see ethernet.txt [1]. |
|
- hisilicon,phy-reset-delays-us: triplet of delays if PHY reset signal given. |
|
The 1st cell is reset pre-delay in micro seconds. |
|
The 2nd cell is reset pulse in micro seconds. |
|
The 3rd cell is reset post-delay in micro seconds. |
|
|
|
The MAC address will be determined using the optional properties |
|
defined in ethernet.txt[1]. |

|
resets = <&crg 0xec 0>,<&crg 0xec 3>; |
|
reset-names = "mac","phy"; |
|
mac-address = [00 00 00 00 00 00]; |

phy-handle = <&phy0>; |
|
hisilicon,phy-reset-delays-us = <10000 20000 20000>; |
