Hisilicon hix5hd2 gmac controller
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: should contain one of the following SoC strings:
|
||
|
|
* "hisilicon,hix5hd2-gmac"
|
||
|
|
* "hisilicon,hi3798cv200-gmac"
|
||
|
|
* "hisilicon,hi3516a-gmac"
|
||
|
|
and one of the following version string:
|
||
|
|
* "hisilicon,hisi-gmac-v1"
|
||
|
|
* "hisilicon,hisi-gmac-v2"
|
||
|
|
The version v1 includes SoCs hix5hd2.
|
||
|
|
The version v2 includes SoCs hi3798cv200, hi3516a.
|
||
|
|
- reg: specifies base physical address(s) and size of the device registers.
|
||
|
|
The first region is the MAC register base and size.
|
||
|
|
The second region is external interface control register.
|
||
|
|
- interrupts: should contain the MAC interrupt.
|
||
|
|
- #address-cells: must be <1>.
|
||
|
|
- #size-cells: must be <0>.
|
||
|
|
- phy-mode: see ethernet.txt [1].
|
||
|
|
- phy-handle: see ethernet.txt [1].
|
||
|
|
- clocks: clock phandle and specifier pair.
|
||
|
|
- clock-names: contain the clock name "mac_core"(required) and "mac_ifc"(optional).
|
||
|
|
- resets: should contain the phandle to the MAC core reset signal(optional),
|
||
|
|
the MAC interface reset signal(optional)
|
||
|
|
and the PHY reset signal(optional).
|
||
|
|
- reset-names: contain the reset signal name "mac_core"(optional),
|
||
|
|
"mac_ifc"(optional) and "phy"(optional).
|
||
|
|
- 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 properties defined in
|
||
|
|
ethernet.txt[1].
|
||
|
|
|
||
|
|
- PHY subnode: inherits from phy binding [2]
